A solution contains one or more of the following ions: Ag +1, Ca 2+, and Cu 2+. When sodium chloride is added to the solution, no precipitate forms. when sodium sulfate is added, a precipitate forms. this precipitate is filtered of and sodium carbonate is added to the solution, which also produces a precipitate. which ions were present in the original solution? write net ionic equation for the formation of the precipitates.
Which one of these equations describes a redox reaction?
