Inorganic Chemistry

I am not a chemist, but I have always thought that some film producers (for example, science fiction) have been making a fundamental mistake. When a strong acid is poured out of its container and then dissolves everything in its path, why does it not dissolve the container itself in the first place?

Where is the best place to buy this chemical (cheap and quality)? Also where do you buy your chemicals?

I am a freshman in college, and I need to develop my own experiment. I was hoping to come up with something original (for example one year, a person wanted to know why people used specific salt to cover roads in winter, so he ended up making his own snow). Right now I'm thinking something with hair products, like relaxers, dies, perms, keratin treatments and how it affects hair what happens chemically. I'm having trouble developing the idea further, so if anyone could help I would really appreciate it!!! Other ideas are welcome also =)

Dear Fellows, If CO2 reacts with soultion of NaOH then we get NaHCO3 solution, Is it possible to exhaust CO2 from NaHCO3 solution by Shaking it or by creating Vacuum on it so it can exhaust absorbed CO2 and we can through it in atmosphere, i am thinking on this logic that if NaOH can absorb CO2 to become NaHCO3 then NaHCO3 can also becomes again NaOH by eliminating absorbed CO2. please guide if it is possible. Please forgive it doesn,t make a sense.

helloooo everybody i need help in some subject, i want a book or any paper for phospines any thing for it,

While boiling a solution, the beaker the solution was in repeatedly made a pinging sound, followed by a bubble rising to the surface. What is this caused by, and should I be worried?

As an experiment, I attempted to make pure MnO2 from the black battery sludge inside a carbon-zinc battery. An 'ingredients' list gave me this for the sludge: Manganese dioxide: 35-40% Zinc: 10-25% Potassium hydroxide (35%): 5-10% Graphite (natural or synthetic): 1-5% This is from a Duracell alkaline battery, but I figure it's close to the stuff I have (might be wrong, though). So, to purify it, I dissolved the stuff in a green (impure) solution of strong HCl, which gave me an even greener (think lime or yellow-green) solution. Then I got some NaOH, dissolved in water, and added that to precipitate out the manganese. However, I have a mixture of brown (supposedly my…

The traditional route to making SiCl4 and SiI4 is to burn elemental silicon with the halogen. While this route is very direct, it requires very high temperatures. It can also be difficult to obtain the silicon to begin with since silica can only be reduced with carbon in an electric furnace. Here is an interesting new alternative: Dissolving CaCl2 into molten zinc chloride (which melts at only 292 °C ), then bubbling in SiF4 (made by reacting silica with hydrofluoric acid). Anhydrous aluminum trichloride has an even lower melting point, 192.4 °C (this surprising number is not an error!) (2)CaCl2 + SiF4 --> (2)CaF2 + SiCl4 The silicon tetrachloride could…

what ratio of CaO:H2O should I use to get the maximum amount of heat?

I am confused about what the difference is between Bond Energy, Enthalpy of Formation, Hess's Law and Enthalpy? The reason being that they all involve heat (ie enthalpy) as a measurement. Enthalpy I know is the heat present in a system. Enthalpy of Formation is the formation of a compound from elements in their most stable/standard state. Bond energy is the heat added to a system to break bonds and then heat is released when new bonds are formed. But the answer that you get in the end of the day is still in terms of enthalpy, correct? If so, then does that mean that if a reaction is exothermic, heat is released, surroundings get hotter, and the bonds formed are stron…

Hey hey people, Im going to be starting a very very long summer soon, so I need to plan what ill be doing (I have approx. 12 weeks!). So, I want to try and make some chemicals and extract some elements from stuff I have at home. So, I require help and chemical knowledge on how to get some of the chemicals Im looking for! So, basically, I can buy about 20 1ml or 5ml jars, and I plan to put the elements and chemicals into these (I dont intend to hold large quantities of anything!). ELEMENTS ACCOUNTED FOR ARE CROSSED OUT! Hydrogen is easy enough (not exactly a challenge!). Helium is challenge, but I reckon if I turn a smoke detector upside down and leave it…

Now, before I start, I want to make this known: Not many people will be able to do this, and if you want to make a big batch, then you'll have to go collect for the cause! So, most of you wont know, but Pyritic fossils (they are common in chalk and at the jurassic coat (thats lyme, seatown and charmouth in Devon)) can get infections. A tiny bacteria, the scurge of collectors, attack the pyrite, breaking it apart. Now, this is infectious: Keep infected fossils with uninfected and the bacteria will jump over eventually. But, what has this got to do with it? well, Pyrite fossils break down into sulphuric acid in humid conditions, which further deteriorates them. The …

I was wondering if anyone had any information on creating a plasma out of mercury gas. I really just want to know if it can be done and at what voltages and amperage should be used. Also a side question what would be the volume equation needed to figure out how much space mercury in a gas form would take up in a closed space. Thank you to anyone who can help.

I almost posted this in the physics forum but I realised that what I am ultimately looking for is a type of substance to use, and the way it behaves will be down to its chemical make-up. I am not a scientist, my only knowledge is from tv documentaries. I am an animator working on a personal project and I wanted to film some liquids interacting. My problem is that I want to film the same type of turbulence as what you see when you pour milk into a cup of tea. The problem is that the turbulent forms which the milk makes are on a scale far too large for the effect I am aiming for, I need the same effect but much more detailed, with intricate micro scale vortices. …

I was looking in a book and I found that the Bond Energy of C-C single bond= 347 KJ/mol double bond= 614 KJ/mole triple bond= 839 KJ/mole Now this shows that a triple bond is stronger than a double which is stronger than a single bond. However, when I subtracted Bond Energies b/w the double and single bond, I got 267 KJ/mole, which is a value less than the energy of a single bond. When I did the same between a double and triple bond, I got 225 KJ/mole. From this, I get the impression that the single bond is the most energetic since it is the most stable, but why is it that as you increase the # of bonds (ie single--double--->triple), the energy of the addit…

Hello, I am new to science forums and I would like to ask, how can you make fine aluminum powder? I need it for a chemistry experiment. :rolleyes:Thanks, Eddie

If you go to Wiki and search 'alkaline battery', you get the picture attached. Wiki says this is pure KOH. So, I was wondering how to force a battery to leak in that way? Would recharging an AA with a 9V work?

Howdy? I'm looking for something unusual that I can do in my classroom demonstration in Chemistry. I have one problem though. I don't know what to do. Who has an idea of a really cool and interesting experiment? The ones which use chemicals that are common and safe. Thank you for considering.

There seems to be much uncertainty of the structure of the oxoacids of certain elements, particularly metalloids, but also of metals such as molybdenum, tungsten (i.e. "molybdic" and "tungstic" acids), and such terms as "perrhenic acid" and "rhenium heptoxide" are frustratingly used interchangeably. Orthosilicic acid certainly exists in solution, but when crystallized from aqueous solution under standard conditions, no-one really knows what happens- perhaps the acid polymerizes, perhaps a hydrous silica is produced. An example of this uncertainty can be illustrated by the compound "Arsenic acid" when crystallized; wikipedia* talks of the structure H3AsO4 ½ H2O, but ho…

Hello, I need the help of a boron specialist/chemist. I had an unidentified substance and I posted a thread in the organic chem topics trying to have it identified. After a friend helped do some tests, he believes that the substance is most likely boric acid. Please check the link below it will lead you to the original topic. You can see photos and info about the substance. My friend is not good with inorganic chem, so he suggested that a boron chemist could probably help me. I would like to find out which type of boric was used, and how to crystallize it like my photo? If you know of a lab or someone who can help and requires a fee, do not hesitate to let m…

In Lewis A/B, an acid is an e- pair acceptor and a base is an e- pair donor. So when an acid accepts e- it becomes reduced in its charge. However, acids are usually found with high ox numbers leading one to believe that they get oxidized. I find the OIL RIG and Lewis Acid/Base definitions to be counter-intuitive. For example, if one asks which of the following is a stronger acid: Ca2+ or Li+, one would say it is the one with the higher ox number, but based on the Lewis definition, wouldn't it be the one with the lower ox number since you are gaining e- (ie - charge) and should decrease in ox #?

Okay, I know there is a thread "NO, you can't make sodium" pinned on this forum, but I had this idea and I just think it might work. So here's what we do: Make the highest concentration possible of [latex]NaCl[/latex] in [latex]H_2O[/latex]. Then we add petroleum, as much as we used water in the first mixture. Petroleum is insoluble in water, it's boiling point is 150 °C and it should only be used to preserve the [latex]Na[/latex] from reacting once separated from [latex]NaCl[/latex]. Then we start heating the mixture while electrolysis takes place. Must be careful not to exceed 150 °C as petroleum will evaporate. So as [latex]Cl2[/latex] is formed and goes away, [latex…

Would anyone happen to know the heat of formation for lithium. Also it would help if someone knew a way of determining the heat of formation of the reactants of a reaction when you only know the products.

Can I purify the Oxalic Acid found in Bar Keeper's Friend? It's about 5-10% oxalic acid.
