Students are investigating solutions. Their lab procedure instructs them to mix salt and water which results in a clear liquid. they place the resulting clear liquid in an evaporating dish. after a week they observe that there are only crystals left on the inside of the evaporating dish. The original solution before evaporation is most likely a/an
