Inorganic Chemistry

Is it possible to combine 3 elements (tholium, silver and silicon) together, such that under the microscope they appear separate and discrete from each other? Therefore each element will be located on the sample seperate from the others. If you melt them together using a furnace you'll find all elements in any one area. Thanks

Hey, I was looking at the reaction between ammonia (NH₃) and hydrochloric acid (HCl). Apparently from the diagram I saw the hydrogen from HCl would get drawn towards the nitrogen, leaving an electron behind for the chlorine. Why does this happen? Do lone pair electrons have a larger electrostatic force? P.S forgive me if I've i may of done something wrong, I'm new to this website.

Hello. I am by no means a science expert. Just a really worried mom hoping to get some information from people who know a thing or two about chemistry and perhaps it’s effects on the human body. I recently read a report where one of the laundry detergents I have been using for my baby’s clothes contains 10,000 ppb of 1,4 dioxane, which is apparently the maximum amount recommended as considered “safe” in these types of household products. Based on the fact that I’ve been using it since my child was born, I’m nervous that this is a significant amount for a child. I know it can be absorbed via skin or inhalation amongst other ways. Does anyone know how much…

Hello guys, why is H3PO4 non oxidizing, even tho the P is at its max oxidation state and can get reduced?

This is a topic that I've been thinking about, but before I ask my question, I just want to give some background info.: In 1804, John Dalton published his law of multiple proportions, which states: When two elements (call them A and B) form two different compounds the masses of element B that combine with 1 gram of element A can be expressed as a ratio of small whole numbers. So, carbon monoxide, CO, has a ratio of 1.33 when we divide the mass of Oxygen with 1 gram of Carbon (Carbon equalling 12.01 g or 12.01 amu in 1g of Carbon). And, carbon dioxide, CO2 has a ratio of 2.66 when we divide the mass of Oxygen with 1 gram of Carbon (again, Carbon equalling 12.01 g…

Hi friends, I'm trying new ways to make bricks more strong by chemicals, I bought some calcium hydroxide and dipped it in crushed bricks and inside the bricks calcium carbonates formed after couple of weeks, I tested it with compression test and the strength had increased slightly. I have basic knowledge about chemistry, but I don't stop testing chemicals. I don't know any other chemicals that would soak into the bricks and make it stronger. I don't make bricks, so I can't add something to the bricks before it's made. So, what I will do is, crush the brick and add some chemicals and test the compressive strength of it. I want to find some other chemicals that wo…

Hello ! Is it possible to produce hypochlorous acid by reacting chlorine gas with water ? Cl2 + 2H2O --> 2HOCl + H2 If it is, is there special conditions for the reaction to occure ? And if it is not, is there another way to make hypochlorous acid ? Thanks

I collect chemical elements. And recently received my sample of Cerium. It is still sealed in its vacuum plastic bag. This is my first lanthanide sample and I chose Ce because it was the cheapest I could find. Bought a 100g bar from eBay. - Can I remove it from its packaging and handle it as any other metal? - Can I keep it exposed in open air as all my other samples? (I don't care about tarnishing). Unfortunately I don't have any airtight places or mineral oil to store it 😕

i recently bought some pond plants which came tied with small strips of lead to weight them in the water. i am unsure as to the toxic potential of these strips in the environment.

Alright, I was doing an experiment with stelactites. To make this short... I took an old, black penny to weigh down a paper towel in a nearly saturated solution of salt, and water. The penny was wrapped in the paper towel, and then submerged in the salt solutiuon (NaCl and H2O). A day later, when I took the old penny out, it was as good as new! Can someone explain this? Will the penny get more rust after soaking in the solution in the long run, or is it a good cleaning??? Is this cleaning method practical for coins, and does it cause any damage??? Thank You.

I've read this new paper by Alexander Sikalov commercial link removed by moderator It says that most hypervalent halogen hydrides should exist and that IH3 & IH5 should be stable enough to be observable. My question is, has anyone tried to synthesize these substances?

Hi, i am doing research for a paper about fires and metals and reactions and stuff and would like to ask you guys about lead from USP batterys. If you had a USP system room with many lead batteries like in this picture, would the total amount of lead still be considered quite small quantities if it leaked out?, and i think it would be very unlikely that most of this lead could get mixed together in a violent fire, so it would create a large steam of molten lead. I was told by a metal exper that he thinks this is true, that it probably would be hard for all the lead to get into a large molten steam that flowed away. He also said this "Also, lead isn’t just present as …

(from a severe amateur, please bear with me) I mixed heavy dilutes of sodium tetraborate and sodium metasilicate which created a whitish, translucent gel with water resting on top. Does anybody know what I just made?

So I've separated chlorine from table salt and hydrogen from water by doing electrolysis on brine (salt water). How can I produce hydrochloric acid? Should I just mix both and ta-ra?

I was wondering if the following set of reactions would be a cheap way to obtain sodium hydroxide or sodium hydroxide solution... If it would work, then I could use my nearly endless supply of cheap sodium bicarbonate (baking soda) to make NaOH, which is a little harder/more expensive to obtain 2NaHCO3 → Na2CO3 + H2O + CO2 (at 200° C) Na2CO3 → Na2O + CO2 Na2O + H2O → 2 NaOH Would this work? Why or why not? I'm only in honors chem, so I don't fully understand what's required to make a reaction happen or not, but this seems plausible... and in addition, I found mention of it on wikipedia at the below links: http://en.wikipedia.org/wiki/Sodium_bicarbonate#Thermal_…

So Pva and borax form a bond, when you convert the borax to boric acid it no longer has that bond. If you add sodium bicarbonate than there is the same or a very similar bond almost like if the boric acid got turned back into borax. So whats the reaction with boric acid and sodium bicarbonate?

"An elucidation of the reaction mechanisms involved has been published [56] . lt assigns the formula (alkaloid H)2 [Co(SCN)4] to the relatively water-insoluble blue complexes formed in neutral-to-basic solutions, and the formula [Co(alkaloid)2] (SCN)2 to the more water-soluble, brownish-red to pink complexes formed in acid-to-neutral solutions. Solubilities in water and chloroform are given for complexes formed with 29 alkaloids and nine metal thiocyanates." Schlesinger Presumably (alkaloid H) is the protonated form of cocaine or other compounds. Experimentally, there are blue crystals initially formed in the reaction, then the solution turns pink upon addition of H…

Hello ppl amateur chemist here Before I begin, I wanna ask if anyone here knows and is willing to teach me of a cheap, workable process to create sodium carbonate? With that out of the way, I want to talk about how I recently become very interested in this useful chemical called sodium carbonate, since it has tons of practical uses (as glass and metallurgical flux, for the production of biodegradable soap, as a cleaning agent and to produce sodium bicarbonate, which is also extremely useful), and so I've decided to try and develop my own process to produce it... since the ones I'm most familiar with (Leblanc and Solvay), are too hard and costly for a DIY setup …

I use Bicarbonate of Soda (NaHCO₃) in my washing machine for my clothes as an alternative to commercially available washing powders. Whilst living in London and thus in a "hard water" region I read that converting NaHCO₃ into Sodium Carbonate (Na₂CO₃) would dissolve better in "hard water", but I have since come to find that all it does is collect and crystalise on contact with <30ºC temperature (i.e. cold) water. The Crystals can be coaxed back into mixing with water if the water is heated up (I usually wash my clothes on a 40ºC cycle anyway), but wanted to know why they crystalise? nb. I convert my NaHCO₃ -> Na₂CO₃ in the oven at 230ºC for 1hr.

I’ve been presented with a one man study that has very little information. The one presenting it is trying to prove that silver is easily excreted from the body. This is the entire materials and methods portion. I know nothing about testing for the presence of silver but this doesn’t seem complete to me. can someone please tell me what’s missing and what they could have done instead? thanks ’ The present study is based on using a 180-volt DC current between a stainless steel container (cathode) and a silver strip (anode) suspended in about a half gallon of distilled water (less than 2 ppm total dissolved solids). The water distiller, a…

Fe --> more than 500 kwh/m3 (Tfus. 1538°C) Si --> more than 1e3 kwh/m3 (Tfus. 1414°C) NaCl --> more than 250 kwh/m3(Tfus. 801°C) Do you think it's possible to store a large quantity of (renewable)energy when a matter changes from a solid to a liquid?…

Hi Are there any way to extract thorium dioxide from the welding rod ? Without the tungsten contamination. There is of course the h2o2 method. But are there any better way ? Thanks in advance

Hi, I am a secondary school student from England looking into advanced chemistry. I have been learning about the nernst equation and am planning an experiment on this topic. I need to measure a change of 0.001 volts (a milivolt) with a starting voltage of 1V. How can I do this, my school has a multi-meter however its milivolt reader only has 3 significant figures (up to 99.9 mV). At 1.001 volts I would need up to 9999 mV. Find attached proposed experiment Thanks Nernst equation experiment.docx

Hello everyone, I have some problems with an ECC-GC system. I should use the system for the quantification of chlorinated solvents in water. I use a protocol, which included the thermal event of the system. My problems: if I go from SPLIT to SPLITLESS, I have a total loss in signal with a flat line (no picks). If I increase the SPLIT, all the picks appear in chromatogram. WHY?? if I try to set a calibration curve, the system gives me an inverted curve: the highest concentration compound responds less than the low concentration one. All these compounds are perfectly linear. (I use fresh mix compounds made at the moment, which inclu…
