Question
An unknown solution is determined to contain either potassium choloride (KCl) or copper (II) chloride (CuCl2). Using a precipitation reaction, how could you identify the unknown? Specificy which ion you would add to the unkown and how the results would identify which compound is in the unknown.

Specificy which ion you would add to the unkown and how the results would identify which compound is in the unknown.Explanation / Answer
adding small amount of NaOH will produce KOH and CuOH2
out of these CuOH2 is insoluble and will precipitate
if no precipitate then KCL is present
