Asked by katie
A piece of Cu wire is placed into 1.00L of a saturated solution of silver acetate, AgCH3COO. When all the Ag+ has reacted, 2.00g of Cu has been used.
A) Write the net ionic equation for this reaction between Cu and Ag+.
B) Calculate the Ksp of AgCH3COO.
Thank you!

1. Cu + 2Ag^+ ==> 2Ag + Cu^2+
2. mols Cu = grams/molar mass = approx 0.03 BUT that's an estimate and you should do it more accurately.
mols Ag = twice mols Cu = approx 0.06
........CH3COOAg ==> CH3COO^- + Ag^+
I.........solid.......0..........0
C.........solid.......x..........x
E.........solic.......x..........x
From above (Ag^+) = 0.06 and that's x. Substitute into the Ksp expression and solve for Ksp.
Ksp = (Ag^+)(CH3COO^-)
Ksp = ?
