Expert Answer

Step 1

The Ksp which is also known as the solubility product constant is used to show the equilibrium which is present between the solid and its constituent ions in a given solution. The value of this constant is used for the identification of the degree up to which a given compound can dissociate into water.

 

Step 2

The dissociation of Ag2C2O4 can be shown as below:

Ag C,O,(aq)
2Ag (aq)+C,0 (aq)

Step 3

The concentration of the Ag+ ions is given to be 2.2×10-4M.

The concentration of the oxalate ions is given to be 1.1&ti...

K-Ag C0
=(2.2x 10 M) (1.1x10 M)
