Question

At $298\, K$, the solubility of silver chloride in water is $1434 \times 10^{-3} \,g\, L ^{-1}$. The value of $-\log K _{sp}$ for silver chloride is ____.
(Given: Mass of $Ag$ is $1079\, g\, mol ^{-1}$and mass of $Cl$ is $355 \,g \,mol ^{-1}$ )

Answer 1

AgCl(s)→SAg+​(aq.) +SCl−​(aq.)
Ksp​=S2=(143.41.43​×10−3)2=10−10
−logKsp​=10

So, the correct answer is 10.
