If a solution containing A+ ions and a solution containing B- ions have just been mixed and [A+][B-] is greater than Ksp of AB, _____.


the solution is unsaturated

precipitation occurs

equilibrium does not occur

the solution is concentrated

Respuesta :

Answer:

Explanation:

In the solution of AB , they are split  to give ions as follows

AB ⇄ Aâș + B⁻

Product of concentration of Aâș and B⁻ in saturated solution of AB is constant .

This is called Ksp

Ksp = [Aâș] [ B⁻]

If product of concentration of Aâș  and B⁻ exceeds Ksp , the equilibrium shifts to the left side and excess ions come out of solution in the form of precipitate. So second option is the answer.
