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!
Write the balanced net ionic equation for this reaction. How many H+ are there in the balanced equation?
