The solubility of PbSO4 is 0.048g/Liter. what is the Ksp of PbSO4? (MMPbSO4 = 303.3)​

Ksp of PbSO4 is 2.5 *10^-8

Explanation:

Given -

Solubility of PbSO4 = 0.048g/Liter

[Pb+2] * [SO42-] = mass/molecular weight of PbSO4

[Pb+2] * [SO42-] =  0.048g/Liter/303.3g/mol = 0.000158 M

Concentration of PbSO4 = moles/volume = 0.000158 M/1L = 0.000158 M

Ksp = [Pb+2] * [SO42-]

ksp = 0.000158 * 0.000158 = 2.5 *10^-8
