1) Get two medium test tubes. Into one, place about 2 mL of a solution of copper (II) sulfate. Into the other add about 2 mL of a solution of sodium phosphate. Note the appearence of the two solutions and then mix them together noting any changes that have taken place.  -Changes that take place -Balanced chemical equation -Balanced ionic equation -balanced net ionic equation
