Question

How many kilograms of salt (NaCl) can be dissolved in 2 liters of water at 25 degrees Celsius? The solubility product constant, Ksp, is 38.65

Answer 1

726 g

Explanation:

Ksp = (Na^+) x (Cl^-) = 38,65
but (Na^+) = (Cl^-) = sqrt (38,65) = 6,2 mol /L
g/L = mol/L x g/mol = 6,2 x 58,45 = 363 g/L
in 2 liters = 726 g
