Q.

At 298 K, the solubility of silver chloride in water is 1.434×10-3g L-1. The value of -log Ksp for silver chloride is ________. (Given mass of Ag is 107.9g mol-1 and mass of Cl is 35.5g mol-1)                    [2023]


Ans.

(10)

Solubility(s)=1.434143.4×10-3=10-5M

Ksp(AgCl)=(s)2

Ksp(AgCl)=10-10

-log(Ksp)=10
