Determination of Ksp for AgCl:
1. Determine Q for the Ag/Cu voltaic cell whem the silver half cell contains a small amoint of Ag added to 1 M KCl
Voltage after adding AgNO3 to 1 M KCl is 0.80 Temperature is 22.0 C
Using Nernst Equation we need to calculate Q. E is 0.080, E0 is 0.47
2. The concentration of Copper in our redox equilibrium is 1.0M. Usung calculated Q what is the concentration of dissolved silver ions after the addition of AgNO3
