What forms when an acidified solution of lithium permanganate and a solution of potassium sulfite are mixed?
Q. If possible, can you give the normal equation as well as the net ionic equation? Thanks!

A. The product will be a solution containing Li+, K+, Mn2+, and SO4 2- ions. Balance this as a redox reaction in acidic solution. Half reactions: Reduction: 8H+ + MnO4- + 5e- ---> Mn2+ + 4H2O Oxidation: SO3 2- + H2O ---> SO4 2- + 2e- + 2H+ Get the electrons in each to be the same - multiply the reduction equation by 2 and the oxidation one by 5. Then add the equations and cancel out anything that is the same on both sides: 16H+ + 2MnO4- + 5SO3 2- + 5H2O ---> 2Mn2+ + 8H2O + 5SO4 2- + 10H+ Cancel the excess H+ and H2O to get the final net ionic equation: 6H+ + 2MnO4- + 5SO3 2- ---> 2Mn2+ + 3H2O + 5SO4 2- The complete ionic equation: 6H+ + 2MnO4- + 5SO3 2- + 2Li+ + 10K+ ---> 2Mn2+ + 3H2O + 5SO4 2- + 2Li+ + 10K+

What are the two following names. LiH(SO3) the 3 is superscript. And And H2S (aq) the 2 is superscript.?
Q. i think the first is lithium monhydrogen sulfite and im not sure what the other maybe hydrogen sulfide. Thanks THE LiHSO3 is all together
Asked by Greg - Wed Sep 19 20:54:27 2007 - - 5 Answers - 0 Comments
A. I believe the first one is lithium monohydrogen sulfite. It is lithium monohydrogen sulfite because it is an acid salt and therefore does include prefixes with the hydrogen (Because depending on the number of available hyrdrogens in acid salts, multiple versions can be created so you must distinguish between them. To do this you distinguish how many hydrogens there are and therefore use prefixes. In acid salts whether it is ionic or binary or whatever is irrelevant.) The second one is hydrosulfuric acid. It is hydrosulfuric acid and not hydrogen sulfide because it is in an aqueous solution (the "aq" part) thus making it an acid not a binary compound.

A. How can you pass summer school if you can't even spell "school"? This looks remarkably like a boatload of homework, and we aren't in the business of doing your homework for you. I rather like helping students understand some sticky point of chemistry, but I'm not about to do all of your work for you. Even the questions are bogus. Look at the first one... "1. Although phosphorus (Z = 15) can be found in compounds with various charges..." Phosphorous isn't found with ANY charges in a compound. Phosphorous forms covalent bonds, even with the alkali metals, therefore, it never has an ionic charge in a compound.

A. How can you pass summer school if you can't even spell "school"? This looks remarkably like a boatload of homework, and we aren't in the business of doing your homework for you. I rather like helping students understand some sticky point of chemistry, but I'm not about to do all of your work for you. Even the questions are bogus. Look at the first one... "1.

Chemistry Question: Qualitative Analysis?
Q. If i have a sample that is black and has many sparkles in it, what are some possible compounds that it could be? Some possible cations are: Lithium Sodium Potassium Ammonium Calcium Strontium Barium Iron (III) Nickel (II) Chromium (III) Cobalt (II) Copper (II) Aluminum Zinc Magnesium Lead (II) Some possible anions are: Acetate Nitrate Nitrite Carbonate Hydrogen Carbonate Phosphate Hydrogen Phosphate Dihydrogen phosphate Sulfate Sulfite Chloride Bromide Iodide. I appreciate all help.

A. You have to do some reactions at least. Take a little bit unknown compound and react with some known compounds such as acid, base, some salts, etc. Or at least dissolve some in H2O to check its solubility. You can not tell what the heck a compound is if just looking at the black and sparkles. Good luck !
