Question

Be sure to answer all parts. Calculate the molar solubility of BaSO, in a solution containing 0.40 M SO ion. x 10 м (Enter your answer in scientific notation.)

Answer 1

BaSO₄ dissociates to form Ba²⁺ and SO₄^2—.

BaSO₄ <—> Ba²⁺ + SO₄^2—.

Since by dissociating BaSO₄ equimolar amount of Ba²⁺ and SO₄^2—are produced thus [ Ba²⁺ ] = [ SO₄^4—] .

The solution contains 0.40 M of SO₄^2— thus the concentration of Ba²⁺ will be 0.40 M.

Thus the molar solubility of BaSO₄ will be 0.40 M = 4× 10^—1 M.
