1) A 25.0 mL sample of a 1.20 M potassium chloride solution is mixed with 15.0 mL of a 0.900 M barium nitrate solution and this precipitation reaction occurs:
2KCl(aq) + Ba(NO3)2(aq) => BaCl2(s) + 2KNO3(aq)
The solid BaCl2 is collected, dried, and founded to have a mass of 2.45g. Determine the limiting reactant, theoretical yield, and the percent yield.
2) A 55.0 mL sample of a 0.102 M potassium sulfate solution is mixed with 35.0 mL of a 0.114 M lead(II) acetate solution and this precipitation reaction occurs:
K2SO4(aq) + Pb(C2H3O2)2(aq) => 2KC2H3O2(aq) + PbSO4(s)
The solid PbSO4 is collected, dried, and founded to have a mass of 1.01 g. Determine the limiting reactant, the theoretical yield, and the percent yield.
