A0.05270.0527 g piece of metal containing an unknown amount of silver is dissolved to form 25.00 ml of solution. to the solution, 35.435.4 ml of 0.02190.0219 m kcl kcl is added, resulting in the complete precipitation of the silver ash agcl agcl . the excess cl−cl− added to the solution is then back titrated with a standard 0.02190.0219 m agno3 agno3 solution. a total of 14.3314.33 ml of the standard nano3 agno3 solution is required to reach the silver chromate end point in the mohr method. calculate the percent silver in the piece of metal.
