Question

Suppose you dissolve a 0.475 g sample of impure (NH4)2SO4 in aqueous KOH. (NH4)2SO4(aq) + 2 KOH ? 2 NH3(aq) + 2 K2SO4(aq) + 2 H2O(l) The NH3 liberated in the reaction is distilled from the solution into a flask containing 50.0 mL of 0.100 M HCl. The ammonia reacts with the acid to produce NH4Cl, but not all of the HCl is used in this reaction. The amount of excess acid is determined by titrating the solution with standardized NaOH. This titration consumes 11.1 mL of 0.121 M NaOH. Whatistheweightpercentof(NH4)2SO4 inthe0.475gsample?
