Inorganic Chemistry

Hello Everyone, I'm new to these forums so I'll introduce myself. I have an avid interest in chemistry, but I am only in high school, so my experiments are rather restricted. I have found that I really enjoy isolating elements from compounds I have lying around the house, or from the chemistry set I just received for Christmas. My project yesterday was a smashing success, and I isolated several grams of pure Iodine. My process was as follows: KI + HCl --> KCl + HI || HI + H2O2 --> I2 + H2O. Then once I had filtered off the precipitated Iodine, I heated it and re-condensed the violet Iodine vapor on a cold vessel, and scraped it off. My next proje…

So, a question popped into my head. Maybe I'm not understanding the dynamics and mechanics of the H2O molecule, but I thought I would pose the question. Why does water trade-off the H+ ion to another water molecule while in equilibrium? Why? Does that not take energy? And as such, shouldn't that eventually decrease the energy in a system, thus reducing water's ability to maintain an equilibrium? I believe the modern belief is that water at equilibrium is always trading off the H+ ion, but that takes an amount of energy, right? Bonds and broken and re-created, right?

Are D-D reactions Self Sustaining and exothermic?

I'm sorry if this has already been covered in any sodium making electrolysis threads, but I was wondering how I could separate the hypochlorous ion from the hydroxide produced, or prevent the hypochlorous ion from being produced? I would like to make some sodium hydroxide this way, but it seems as though the OCl- is a hurdle. Thanks for any help. Merged post follows: Consecutive posts mergedI guess I could have two chambers linked with a salt bridge, but then I would have a mixture of sodium chloride and sodium hydroxide in the cathode chamber. Is there a way to separate the salt from the hydroxide would be the better question? Thanks

we need to know the isomerization enthalpy for cis/trans butadiene for a p chem lab report. can anyone tell us where we can possibly find this?? help is appreciated. thanks

I recently read about industrial level Nitric Acid and Sulfuric Acid. The two were between 98-99% concentration and the Nitric acid was defined as "Red and Fuming" . I was wondering, is it possible to -using distillation - create solutions of these molarities without F-ing up your lab equipment ? Oh and I know, this is not something to try at home .

Hello, can I purify the potassium nitrate from this fertilizer? 14-5-38 nitrogen(N): 14% phosphate(P2O5): 5% potash (K2O): 38% Boron: 0,014% chelated copper: 0,011% chelated iron: 0,07% chelated manganese: 0,035% molybdenum: 0,007% chelated zinc: 0,035% Chelating agent (ethylene damine tetraacetate): 1% Thanks.

well today I tried the experiment with sodium acetate and water but it didn't work. I used sodium acetate from a chemistry lab (so it is pure...), I put sodium in boiling distilled water for a super-saturated solution: 160 gr in 30 ml of water and I left it on the heater for some minutes. i put the solution in fridge but the solution crystallize in few minutes instead of stay fluid and i cannot use for make instantly "hot ice"... where I made a mistake?!? thanks a lot!

the oxidation of H2O2 is not very strong.i do not know whether P4 can react with H2O2. please help me

What happens when an atom in a molecule undergoes radioactive decay? Say for example you have trisodium-22 citrate, and the sodium decays to neon. What are you left with? Neon gas and a citrate radical? Something else?

Could anyone guide me as regards: 1. Iodophor - method of manufacture in laboratory. Is heating necessary. 2. What difference does it make in manufacture if you make use of Iodine crude and Iodine crystals, 3. What is the highest strength (in %) that could be manufactured

Hi there everyone! Why do Cr and Cu not follow the other d-block metals in electron configurations? We have this: [math]1s^22s^22p^63s^23p^63d^34s^2[/math] (Sc) [math]1s^22s^22p^63s^23p^63d^54s^1[/math] (Cr) ... [math]1s^22s^22p^63s^23p^63d^84s^2[/math] (Ni) [math]1s^22s^22p^63s^23p^63d^{10}4s^1[/math] (Cu) My question is this, I can see why Cr forms the structure it does - the electron arrangement is more stable as it only has one electron per orbital (In the d and s shells) so there is no electron replusion and hence more stable but Cu makes no sence. Can someone explain why these elements behave the way they do? I have been trying to think of re…

I was just wondering if phosphoruous can react with steam? I know it has no chemistry with water but I reckon that it might react with steam in gaseous state/form i.e. P(g) What you guys think? throw in your idea, comments etc they are welcome.

i want to know how can i deal with the yellow phosphorus which is not pure and useless in the lab safely and environmental-friendly.please help me

BOMBS ARE DANGEROUS. Alright, if you've ever wondered if you can make a bomb with sugar, yes you can! I just made one and it was pretty good. It sounded like a gunshot, and the tin it was in didn't land for a while after the explosion. For anybody who is interested, here's my mix: 35% sugar, 63% potassium nitrate, and 2% red iron oxide. I have never heard of anybody else using this as an explosive, but, sure enough, it worked! Far cheaper than making black powder (not to mention much easier to obtain the ingredients and make). Just putting this information out there for people to use. I have purposefully left out how to make a bomb with this formula, so if you don't k…

Been out of school too long and need some help. I want to make a 15% potassium chloride solution from a 100% potassium chloride powder. How much powder should I mix into a set volume of water (e.g. 1 liter)

I am having some trouble with this question. To solve the problem below, you must write clear and convincing justification for accepting one of the possible answer choices as best or most appropriate and for rejecting each of the other choices as less appropriate. Your reasons for rejecting choices are just as important as your reasons for choosing the best answer. 1. Although water is a small molecule, it has some properties characteristic of a large molecule. Why isn't this behavior a contradiction? a. Hydrogen bonds between molecules last only for a very short period of time. b. The small water molecules for hydrogen bonds between many individual molecules. …

So I bought ammonium phosphate monobasic, thinking it was just the ammonium phosphate to use as a fertilizer for algae growing. Then I realized it's the acid form and will lower the pH. Is there a way i can convert ammoium phosphate monobasic to just the ammonium phosphate itself? Or should I counteract the pH change with ammonium hydroxide? Thanks for any help

is there any common to find mixture or liquid that can be used to substitute sulfuric acid? im trying to find something not as dangerous as this acid so i can preform some acid scarifcation on some seed(smooth sumac) i have and need to be able to have them germinate for one of my science classes to show how some acids effects on plants.n if there is any possible substitutes, how long would i leave the seeds in the substitutes if im soposed to leave the seeds in a misture of consitraded(sorry forgot how to spell for a second) and water?

It came from an instant cold pack (so it's enthalpy of dissolution is pretty high.) It utterly failed a test for nitrates, melts into a clear liquid under the heat of a blowtorch, and decomposes upon further heating to form a steamy gas and a white compound with a very low solubility in water. (No the cold pack did not say what was inside it besides the water pack.)

Hi, YT this is aimed you really, how do you make your hydrochloric acid? I've been thinking about how to make it. I thought of a fun way. make 2 electrolysis cells. one has salt in it (table salt) the other just water Build some tubing etc and mix them just b4 burning. this should make water and HCl. I've burned Hydogen oxygen mix in a homemade burner, which heated the burner to a nice white (very very bright). So I've got no troubles there. I take it there has to be a much better why then burning them? Well anyway I could make hydrogen and Cl in a better way Al/Na(OH) mix and bleach/acid mix. Any ideas. chems are limited as I've not got …

Consider: HI + Cl- <--organic solvent--> (eqm) HCl + I- Probably the eqm bias to the right, following the principle of strong base gives a weak base upon neutralization, it seems to be right to claim I- is a weaker Lewis base than Cl-. But my professor said I- is indeed stronger, why is that? It may be related to the polarizability of I-, which is bigger and electric charge more delocalized, thus being more polarizable than Cl-. This makes it more reactive towards a haloalkane than Cl- does. While on the other hand, as electric charge on I- is more dispersed than in Cl-, I- is more stable than Cl-. So a more stable I- reacts more rapidly than a less stable Cl- t…

Hey everyone, I was just wondering in the VO(acac)2 which is a Vandium (IV) complex the V=O bond length is significantly shorter than V-O bond length so the discription that it has a square-pyramidal geometry is somewhat misleading. what do you guys thing? I know that in books and at various places it is stated to be square-pyramidal. I am also suspecting some distortion because of the Jahn-teller effect? your opinion on that is welcome. PS. I just realised I said Jahn-teller distortion which is obviuosly not possible for this complex.

A dry cell has limited life. My friend told me there are two reasons -- what are they?

I found this a couple days ago, so I tried it today. It actually works, I am just wondering how?
