Inorganic Chemistry

I am quite interesting in this.... in water, there are H+ and OH- being attracted by the partial charges of H2O.... but I never see mere Hydrogen Hydroxide.... Why is that??

So...can anything be done with sodium nitrite? And I dont mean drugs 'n stuff. I mean can it be used to make fun explosions and such. Also, could it substitute for NaNO3 when making KNO3? If so, would the resulting KNO2 be similar to KNO3. Thanks

Last week i was interested in how a INSTANT cold pack works. So I opened the pack up and the ammonia nitrate was wet but not cold. Maybe the gel water pack leaked some time ago and the ammonia nitrate got cold but it only stayed cold for a certain amount of time(about a month)? And then when i opened it up it was dead like a battery with no power? So if I were to dry out the ammonia nitrate and put it in a zip lock bag and then pour water in it would it get cold? Or has it lost it's power like a battery? I think it is ammonia nitrate because i remember hearing somewhere that it gets cold with water.

Suppose u let an acid sample sit for a week, does it lose weight after a period of time? and a base sample gain weight after a period of time? why is like this? and when a sample gains weight, the melthing point rises. is it because of the increased intermolecular forces? thanks

I've not found anyother sites that sell argon gass, but this was the first place I came across, they also sell pure o2. £15 for 2 x 1li bottles ( 2 x 60li of gas) What do you think? http://www.welduk.com/Results1.asp?Category=37

Why does aluminium so readily form an oxide layer on its surface compared with other metals? What does Iron(II , III) means? Fe3O4 II= FeO III=Fe2O3 I recognised that it is the sum of the two oxides, but shouldn't it be the mean of the two oxides? Also, is the reaction of potassium reaction a displacement reaction?

The other day when i was at the store i found a bottle of floweasy drain cleaner. The bottle says it contains "virgin sulfuric acid and 12 buffers". What's the deal with the 12 buffers and how will they affect other reactions? Would this be an acceptable replacement for getting the acid out of old/new batteries? Does anyone know how much acid there is in a battery?

I'm not a great chemist, I dont even know if this anything that could happen. What temp would you need carbon rods to be to turn into co2?

i tried a solution of KSO4 and NANO3, and also KCL and NANO3. I cant seem to get the KNO3 crystals. plz help :P thanx guys

A while ago, I was discussing some stuff with a random person in this chat, and somehow our conversation drifted off to not trusting your sources. As an example, he told me not to beleive that the forests are our main source of air. He said that salt and Co2 (I think) create air when they meet. Since salt is running rampant in our seas, this, if it's true, could very well make trees obsolete as it were, in terms of us needing air from them. I'm only talking about air here, I know trees are important for a whole slurr of other reasons, but I'm only talking about air here, breatheable air. So my question: Does this chemical reaction exist? Something like it? If so, woul…

How many shells does a hydrogen atom have? I thought it only has 1 shell, because according to the periodic table, the row number indicates the number of shell (orbit) as Hydrogen is placed in the first row. Secondly, if it has only 1 shell, does that mean hydrogen can never loose 1 electron in its only shell? because otherwise it obtains no electron at all in its shell during ionic bonding. Any help?

A lot of us here know that fluorine is incredibly reactive and amazingly toxic. I'm just wondering if there's anybody here who works with the pure element and/or knows a ton about it? The reason I ask is because I've come up with a way to generate the pure element that I think may work. You would start off by taking a standard glass tube that is maybe a foot long and heating the bejesus out of it. This would be to keep any and all water out of the tube, and to burn out any loose chemicals in the tube. It would basically be sterlizing and cleaning the tube with a ton of heat. (Basically heating the glass a small bit below it's melting point. You would then go and…

I am studying radioactive decay at the moment, and when it comes to writing equations with alpha, beta particles, positrons, protons, neutrons and gamma rays, I don't understand under what circumstances an element would emit gamma rays. (i mean, i know for eg. alpha particles are emitted when an element has too many protons and neutrons) What about protons? Neutrons? THanx

Why do hydrogen chloride dissolve in water gives the ionization of hydrogen ion? And then why does the ion combine with water molecule to ionize to form hydronium ion? What's the difference between oxidation-reduction reaction and displacement reaction?

HELP ME!! For which of the following equations is the enthalpy change at 25°C and 1 atm equal to DH(HCOOH(l))? a. C(s) + H2(g) + O2(g) HCOOH(l) b. C(s) + 2H(g) + 2O(g) HCOOH(l) c. C(g) + 2H(g) + 2O(g) HCOOH(l) d. CO2(g) + H2(g) HCOOH(l) e. CO(g) + H2O(l) HCOOH(l)

Sorry, I've had no chemistry classes yet or anything. I don't have much background knowledge on it either. But what machine or what device can create a spike of positively charged ions? The space it covers has to be about 6 ft by 6ft by 6ft. Seismic activity can cause periodic electromagnetic field fluctuations. What machine can generate the same intensity? Again, sorry I have no idea what I'm talking about.

i'm trying to compile some data for class, and would like to know, when you add an element to a flame, and that flame changes color (magnesium=white, potassium=violet, and copper=green-blue) is the resulting color of the flame related to the element's spectral signature, or whatever that's called? And most importantly, is there a site i can go log onto to find what color each element burns, as well as their spectral signature, if they are different.... i'm particularly interested in cobalt, gold, silver and platinum.... i'd really appreciate some help, Thanx

i have a nice large bottle of 40% hydrogen peroxide. unfortunately it is white and viscous. the other ingredients (aside from water and hydrogen peroxide) are: cetaryl alcohol, cetareth-20, stearic acid, cetyl alcohol and phosphoric acid. i froze the solution and the hydrogen peroxide didn't come out. that's not cool at all. it was just a white solid. how can i extract the peroxide?

Will anyone guide me to internet sites for highly technical exchange of views regarding chemical technology;material handling;inorganic chemistry, finding books on inorganic chemistry?

Well concurant to the expencivity of buying elements I have decided to make my own, allthough could do with a little help. So how can i extract chlorine and silicon for starters?

Hi..I have an urgent and a good question ( sorry for this ).We all know that salts dissolve faster in the presence of growing heat ( increase ), but when it comes to CaSO4 and Ca(OH)2 , the opposite is correct.Their solubility decreases when the heat rises !..any idea why ? taking in mind that they are exothermic. Thanks a lot for sharing and help

Which bond of the above in a particular formula unit or molecule is stronger? Personally, I think covalent bond is stronger. Many ionic substance dissolve in water to give ions out but no molecules, like oxygen , hydrogen....

Can anyone help in suggesting method to manufacture Dicalcium Phosphate Anhydrous CaHPO4 [Mol.Wt.136] with no water of hydration from Commercial Grade Phosphoric Acid at Standard Temperature and Pressure?

what would be the procedure in making KNO3 with KSO4 and sodium nitrate? thanx phoenix

as it says on the tin, where can I find proton exchange membrane (pem) to buy, either the USA or UK, I've found one place that sells them but more would be nice to look at prices etc. Thanks for any help anyone can give.
