2.4414 g sample containing KCl, K2SO4and inert materials was dissolved in sufficient water to give 250 mL of solution. A Mohr titration of a 50 mLaliquot required 41.36 mL of 0.05818 M AgNO3. A second 50mL aliquot was treated with 40 mL of 0.1083M NaB(C6H5)4. The reaction is NaB(C6H5)4+ K+ KB(C6H5)4(s)+ Na+. The solid was filtered, redissolved in acetone, and titrated with 49.98mLof the AgNO3solution according to the reaction KB(C6H5)4+ Ag+ AgB(C6H5)4(s)+ K+. Calculate the percentage of KCl and K2SO4in the sample.
