The Total solution for NCERT class 6-12
If the solubility product of CuSis 6 × 10−16, calculate the maximum molarity of CuS in aqueoussolution.
Solubility product of CuS, Ksp =6 × 10−16
Let s be thesolubility of CuS in mol L−1.
Now,
= s × s
= s2
Then,we have, Ksp =
= 2.45 × 10−8 molL−1
Hence, the maximum molarity ofCuS in an aqueous solution is 2.45 × 10−8 mol L−1.
