Question

Determine the equilibrium constant associated with its solubility, the solubility product, Ksp 1. Show how the value of the solubility product is independent of the presence of initial common ions. 2. It turns out that the value of Ksp depends slightly on the presence of "uncommon ions", that is, spectator ions that might be present in the solutions. So, adding common ions with their associated spectator ions cause rather complicatecd changes in molar solubility and Ksp. To avoid these complicated fluctuations in our measured Ksp values from different concentrations of spectator ions, al solutions used in our measurements contain a large excess of NaNO, spectator ions.

Explanation / Answer

1,

The solubility product is related to solubility,which can be explained as follows-

Ag2CrO4?2Ag+ +CrO42-

S                     2S          S

Ksp=[Ag+]2 [CrO42-]

=[2S ]2x[ S]

=4S2 x S

Ksp=4 S3
