Question - A solution contains one of more of the following ions: Hg2 2+, Ba2+, Fe2+. When potassium Chloride is added to the solution, a precipitate forms. The precipitate is filted off and potassium sulfate is added to the remaining solution, producing no precipitate. When potassium carbonate is added to the remaining solution, a precipitate forms. Write net ionic equations for the formation of each of the precipitate observed.
This is not a problem given in the book, so I just need the full solution of deriving!
A substance, C, decomposed by water is initially dissolved in water (at t=0) to form a 1.0M solution. At the end of 100,000 s, 50% of C remains unreacted. What percentage of C will remain at t=1week if the reaction is second order in C only to 3 s..
