For Bi2S3, Ksp = (2s)^2 (3s)^3 = 4s^2 × 27s^3 = 108s^5 or s = √(Ksp / 108) = √(1 × 10^-17 / 108) For MnS, Ksp = s^2 or s = √Ksp = √7 × 10^-16 For CuS, s = √Ksp = √8 × 10^-37 For Ag2S, Ksp = 2s^2 × s = 4s^3 or s = (Ksp / 4)^(1/3) = (6 × 10^-51 / 4)^(1/3) Thus Bi2S3 has maximum solubility.

1. Ksp = (2s)^2 (3s)^3 = 4s^2 × 27s^3 = 108s^5
2. s = √(Ksp / 108) = √(1 × 10^-17 / 108)
3. For MnS, Ksp = s^2
4. Thus Bi2S3 has maximum solubility.

Correct answer: Thus Bi2S3 has maximum solubility.

Solution

The solubility product (Ksp) calculations for Bi2S3, MnS, CuS, and Ag2S are correctly performed, and the conclusion that Bi2S3 has the maximum solubility is accurate based on the given data.
