You enter the lab to analyze the chip filtrate for Cl?. First, you prepare a solution of silver nitrate, AgNO3, and titrate it against 0.500 g of KCl using the Mohr method. You find that it takes 62.7mL of AgNO3 titrant to fully reach the equivalence point of the reaction. You then use the same silver nitrate solution to analyze the chip filtrate in a Mohr reaction, finding that the solution yields a rusty brown precipitate when 47.9mL of titrant...
