Problem: A 1.013-g sample of ZnSO4•xH2O is dissolved in an aqueous solution containing excess BaCl2. When they react, BaSO4 and ZnCl2 are formed. The pure BaSO4 product is filtered out of the solution, dried, and its mass is determined to be 0.8223 g. What is the value of x in ZnSO4•xH2O?

FREE Expert Solution

We are going to determine the value of x in ZnSO4•xH2O


First, let’s write the balanced equation for reaction

ZnSO4•xH2O + BaCl2 → BaSO4 + ZnCl2 + xH2O
