What would happen if you put some francium in some hot hydro florous acid?

How do you make nitric acid HNO3 and KNO3? WITHOUT using oine to make the other (and no im not dropping potassium into nitric acid, mainly due to the fact I dont want to die yet). Using household materials, (purification of fertilizer?) Im NOT a terrorist, just 14 and want to do some experiments in my back garden.

if like silver nitrate solution undergoes electrolysis, using both silver electrodes, what will be the produc at anode!? i've seen silver dissolves to form silver ions as well as oxygen is produced, which one is correct!? i know OH- is a stronger reducing agent than Ag... thx~( sorri for asking such a silly question )

I need to know if you could give me a report on the Similarities & Differences on Salts, Acids, & Bases Thanx So Much JJ

Can anyone please tell me how fast these reactions will occur. Haven't done the experiments yet, so I'm mystified Zn(s) + CuSO4(aq) ==> ZnSO4(aq) + Cu(s) Zn(s) + Pb(NO3)2 (aq) ==> Zn(NO3)2 + Pb(s) Any help would be much appreciated. Thank you.

I was making copper sulfate, for some reason it turned blue over night :S i need help lol

how do i crystalize this compound i made? Hopefully i will get copper sulfate. I dont have a bunsen burner at home. So i need to use the kitchen(i had to con my mum into letting me ) I have a beaker. Do i heat the mixture to boiling point then let it sit to form crystals or do i evaporate it.

hey, i just tried to make copper sulfate by electrolysising it in a solution of vinegar and epsom salt. on the copper it is forming a black solid. it is soft. But the good thing is the solution is turning blue . i will crystalize it tomorrow.

whats potash? Can i use it to make KNO3? if i can that will be great, cause i can buy the stuff from the chemists

Nitrates are used in lots of oxidising ways; Saltpeter in Gunpowder and Nitrous Oxide in cars; but why are nitrogen compunds so used in these situations?, why are they so good at supplying oxygen? Why arnt other oxates used, and would those work?

What is per e.g Hydrogen PERoxide?

Why is flourine so reactive? If it is because it has one spare electron space close to the nucleus, why isn't hydrodgen more reactive?

Carbon is meant to be the base of life as it has half an electron shell on the outside. Well so does hydrogen and a few other elements, so why arnt those as special?

I have recently started very basic chemistry for a science club at my school. I was wondering if anyone has some tips on electroplating. Does anyone know of some good objects to electroplate with simple and common household items? Detailed reactions and procedures would be very helpful and appreciated. Online lab manuals may help.

being a little bored this morning, I decided to electrolyse some Ammonium Sulphate just to see if I could make Ammonium Persulphate, then an idea struck me, ammonium persuphate dissolves copper. so, if one were to have a huge vat of this and an elecrtrode at either end with a current passing through, one could throw in loads of scrap copper any shape into it, and reclaim the pure thing at one of the electrodes, it could carry on nearly forever. unlike using the scrap AS an electrode and doing it with say Copper Sulphate soln, where you`de be stuck if your scrap was little copper stampings or unviable shapes AND you`de have to change 2 electrodes! this avoids all that, t…

Please can somebody tell me how to make AP out of newspaper (its the carbon i think). Please....I know its possible. Oh yeah, you can use cotton wool somehow as well)

Hello, this is my first post. Is it hypothetically safe to mix potassium ferrocyanide with a weak acid like citric acid at room temperature, or would this produce deadly cyanide fumes, and it's best not to do this? I'm guessing it's probably not safe, and I wouldn't try this myself or reccomend it. I need to point out that I speak of potassium ferrocyanide, and not the much more toxic and dangerous potassium cyanide. The reason why I ask this is purely academic and from a hypothetical standpoint. EDIT: What would the resulting mixture of potassium ferrocyanide and citric acid at room temperature be anyway? Would the mixture be deadly cyanide? (not …

Can anyone help, I am having problems understanding reactions involving the transition metals, particularly their electron configuration and valency. I have recently learnt that each shell has subshells s, p and d. What is the d subshell and is there a reason why you get electrons 2 in s, 6 in p and 10 in d. Does an atom with a d shell need 10 electrons instead of 8 in it's outer shell to be inert? How can the valency / oxidation number be calculated from the atomic number? is there a formula that will work for all elements? I had been thinking along the lines of: 4 - (electrons % 8) which gives the number of electrons above or below inertness, but i d…

I have tried electrolising saturated NaCl solution using graphite electrodes where i collected gas at both electrodes. I was expecting green at the anode: a clear gas was produced. Thinking that I had some oxygen I took sniff of it and it stung my nose with a strong chlorine smell. Is the chlorine forming HCl before it makes it to the collector? What is the smelly, colourless gas produced at the anode? (I noticed a slight whitish wispy vapour/gas coming from the solution) How can I make chlorine gas without using MnO2 + HCL or molten NaCl? according to WebElements it can be produced by electrolysing brine. Thanks for any help.

If i wanted to grow salt crystals to their original shape (Cuboid, i think), how would i actually do it. I know the basics, like make a saturated solution, but how should i grow the seed crytal and how to obtain it Thanx

I have a piece of Americium 241 at .9 microcuries. I placed it on a glow in the dark sticker and in about 30 seconds, the sticker starts to loose its glow. The americium is emitting a strong alpha radiation, but I am unsure of why this is happening. Can anyone fill me in?

hi all, I have recently taken an interest in chemistry and am currently learning the basics. So any advice/answers from you folks would be great as an alien subject can be a bit confusing when starting out. I have noticed two strange occurences when electroplating a ten pence with copper and when using old stainless steel cutlry for electrodes. I first noticed that there is a pattern to the way stainless cutlery corrodes when used as an anode(hopefully my mother wont), I used a jam jar with 2 parallel holes cut in the lid through which i put 2 identical knives, insulated where in contact with the lid. The face of the knife, used as an anode, that faced the catho…

Does Uranium become a lot more stable when it is in a compound? Would it be possible to stablise some of the very heavy unstable elements made in Cyclotrons by quickly turning them into a salt? Just aman

When we start building the elements 120 and above on the periodic table, do you expect some will be super strong, radiation resistant, maybe super conductive or super insulators? The problems we face now with space travel vulnearablilities may someday be eliminated if we have new materials better than what we have now. Do any of the elements exist naturally in the universe? Just aman

I was wondering how this molecule is built up. It is a molecule of carbon and silicon. I was just ondering whether it would be like a salt and have a crystalline structure or whether it can be seen as a C-Si molecule bonded by a quadruple bond??
