1.
A standardized KMNO4 solution can be used to analyse compounds of unknown composition.
One such compound is hydrated calcium oxalate, CaC204-x H2O. The degree of hydration is
usually not known and may be determined based on the balanced equation below, by titrating
a weighed sample of the hydrated calcium oxalate with KMNO4.
5 H2C2O4(aq) + 2 MnO4 (aq) + 6 H*(aq)
→ 10 CO2(g) + 2 Mn2"(aq) + 8 H20(1)

If a 0.3215 g sample of CaC204-x H2O required 32.28 mL of a 0.02426 M KMNO4 solution,
what would be the value of x? (Round your answer to the nearest integer.) Show all your
calculations. Write the formula of the hydrate.
