2. Unspecified amounts of CaCl2 + 2H20 and K2C2O4 H2O were reacted and the calcium oxalate precipitate was allowed to settle to the bottom of the beaker. Two samples of clear supernatant
were tested for the presence of unreacted ions by adding calcium chloride to one sample and
potassium oxalate to the other. The sample in which calcium chloride was added showed the
formation of a white precipitate whereas the sample in which potassium oxalate was added
remained a clear solution. From this profile, identify the limiting reactant. Justify your answer.
