Question

At a certain temperature, the solubility of strontium arsenate, Sr3(AsO4)2 , is 0.0660 g/L.

What is the

Answer 1

The solubility of strontium arsenate is 0.0660 g/L

Its Molar Mass: 540.6984 g/mol

0.0660 / 540.6984 = 1,22x10^-4 mol/L - molar solubility

[Sr²⁺] = 3 * 1,22x10^-4 = 3,66x10^-4 mol/L

[AsO4^3-] 2 * 1,22x10^-4 = 2,44^-4 mol/L

Ksp = (3,66x10^-4)³ * (2,44x10^-4)² = 2,9x10^-18
