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.

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
