I have a LAQUAtwin Salt 11 which has a NaCl mode and ranges from 0ppt to 100ppt (or 0% to 10.00%). I am wanting to work out the Na concentrations from the NaCl and I want to convert the Na component to Milli-equivalents per litre. I can't seem to find any information on the net to help me. Could anyone please help educate me with a worked example please? I would really really appreciate it. Thanks for looking and my kindest regards to all. newbie Chris

I was trying to make sulfuric acid from the sulfur in pyrite when somewhere along the way something odd happened. I was dissolving the pyrite in nitric acid while heating it around the nitric acid's boiling point to get a yellowish solution that I am not sure what it is, but I would imagine that it is some mixture of sulfur and something else. I let this happen until there was no more NO2 being released and a satisfactory amount of the pyrite was dissolved. A small, clear salt was formed during this and everything was filtered so I was left with the yellow solution. This is the point where this mystery starts. I boiled the solution to make sure none or little water w…

Is the crystallograhy for unique? Why is it saddle conformer shaped, is it related to diagonality on the periodic table as silicon relates to boron?

I was wondering if magnesium sulphate can be used as an oxidizer in fuel-oxidizing agent mixtures since it contains oxygen.

Hey everyone, I hope the question is not off topic. A few days ago I made a saline solution (45g salt and 180ml of tap water) in a stainless steel pan. This solution was boiled to dissolve the salt and used to add a specific amount of salt to a beer I made, a german style that is traditionally made with salty water. While I was dosing the salt in each bottle I noticed that the solution had turned sligh yellowish, but at first I assumed it was just some salt impurity. However, a few hours after bottling I came back to wash the pan and realized the salt had started to corrode the bottom, and at that point there was some stuff floating and visible areas of corrosion. No…

I am ordering a glass distilling apparatus and i was wondering what all can i do with it i am 16 and love science and robotics and i need help Sincerely, Ethan

Hello all. I am looking to increase my h2o2 concentration from around 12% to around 24% for an elephant toothpaste reaction. I am aware of the method using a vacuum pump, the methods involving freezing, and the methods that heat the material up. Which of the last two would be safer, and which of the last two would be easier to control the percentage? I don't want to end up with an extremely angry oxidizer like high percentage h2o2.

I learned from a source that when external magnetic field is applied, parallel spin/spin up has lower energy than spin down. But why? How does this relate to two like poles of magnets facing each other and two unlike poles facing each other? Source:https://mriquestions.com/energy-splitting.html

I tried to grow some Salt crystals a while back, it worked using table salt, however this also contains Sodium Ferrocyanide. Would I be better using pure Sodium Chloride (from a chemical supplier) ? I think the crystals should be more cuboid shaped, which I think is how the molecular structure is for Sodium Chloride. I have attached a photo of my previous attempt results. I am not what the Sodium Ferrocyanide does, it is an anti caking agent or something. so that may explain the results. Thanks Paul

Hi everyone, I am developing a project to raise awareness about drink spiking. I was thinking what if we could create sone sort of straws that turns on another colour when the drink is being spiked? Currently is completely hypothetical, but I would like to understand if concretely is possible. If so, would be best to have the straws with lines (which would change colour) or any design could be applied?(like stars, or typography). As well which colour would be actually doable? thank you for your help Sara

It appears that talc is magnesium silicate and some natural asbestos-types, are the same compound. Is it the physical structure, due to geological stresses, that defines the difference?

Hello, in which chemical reaction is the highest sedimentation rate observed? The chemical reaction must be between two true solutions. Thank you.

Hello to any wonderful scientist reading this,this might be and can be a really foolish doubt (because of which I seek my deepest apologies for posting in a intellectual and scientifically tempered community,where many of you are also too busy to handle such queries) but this is really bothering me lately . Isotopes are atoms of the same element having same atomic number but different mass number . This means that they differ in their physical properties(since the protons And electrons are same in number And neutrons are different, and the neutrons are the subatomic particles which influence the physical properties of an element ) And we generally refer the physical …

Would “rock wool” work to filter the gold foils from an electrolysis stripping cell operation? Paper filters are no good…

I have been relying on washing my clothes with bicarbonate of soda and white vinegar (separately) for a few years now, and wondering now if it’s actually leaving my clothes as clean as I thought ? I cannot send a sample off to a lab to be tested for bacterial growth, so I thought that I would go though Persil’s ingredients list to see what they were using and how they justified it, as well as how Bicarbonate of Soda and White Vinegar compares ? I originally went this route to cut out all the man made chemicals that I didn’t understand. If I understand them better, I may well make my own washing powder, just with the least amount of chemicals to get the job done. …

My chemistry teacher mentioned that the acidity of HX compounds increases down the group (i.e. HF<HCl<HBr<HI), and I get why it is so (because the atomic radius of the atom increases down the group => bond length increases => less attraction between H+ and X- => donates H+ more readily). But whenever I search for strong acids online, they only mention HF and HCl, while HI is very much stronger than those acids. Why is it like that? Is it just because they are more well known? Or is there another reason?

Is it possible that the hydrogen obtained via brine electrolysis is contaminated with sulphur compounds?

A basic doubt in molecular orbital theory. While writing the electronic configuration of molecular orbital, for example say of Fluorine molecule, which forms a single sigma bond between sp3 orbitals, we start the configuration with sigma1s² orbital. Does this mean molecular orbital theory considers that when atoms combine, all of their orbitals are fused? Even the ones not participating in the bond? Or does it consider that the bond between atoms is not just a result of the bond between valence orbitals, but all of the orbitals of combining atoms? I have only been introduced to this theory qualitatively, so the questions may seem a bit weird.

Why are representative called so? If I google it, the majority of people state its because their outermost energy levels are not completely filled. But isn't it absurd to name them "representative elements" then? what is the logical reason behind it?

I just learned that there are three kinds of overlapping (positive, negative and zero). I don't thoroughly understand the concept of different signs in orbitals and their overlappings. What does difference would it make if the signs are different (negative overlapping happens) when they don't really play a significant role? Could someone explain how waves and orbital shapes along with overlapping in brief?

Hi All, One of the pH adjustment programs I use takes the amount of Boron in the water into account. I'm not sure it matters - So I'd like to know if the Boron concentration in pool water affects the amount of Hydrochloric Acid required. If so, how? Is there a formula I can use to adjust for the amount of Boron? Thanks in advance, Buddy.

How do I draw these? I need 15 shapes of d orbital and 21 shapes of f.

Would it be possible to have, say, calcium cations in aqueous solution, react with O2 to form calcium oxide, if the concentration of the dissolved gas was high enough?

I've been using potash as a cheap, very abundant basic chemical. I've also been aware that, if you burn it, you'll decompose the carbonates and get the even more basic potassium oxide. I just wanna know: if I hydrate the potassium oxide (I know it can be dangerous), will I end up with potassium hydroxide?

Hi! I have accidentally spilled a few milliliters of an acid mixture (Nitric and hydrochloric) into a bottle with commercial Urea beads. How can I can get back the purified Urea? Is there a suitable solvent to use for recrystallization? Or is there another method to do it? Thank you in advance!
