If x represents the molar solubility of Ca(OH)2 , what is the correct equation for the K sp ? Ksp=x^2
Ksp=2x^3
Ksp=4x^3
Ksp=x^3

Ksp = 4x³

Explanation:

Step 1: Write the reaction for the solution of calcium hydroxide

Ca(OH)₂(s) ⇒ Ca²⁺(aq) + 2 OH⁻(aq)

Step 2: Make an ICE chart

Let "x" be the molar solubility of calcium hydroxide.

        Ca(OH)₂(s) ⇒ Ca²⁺(aq) + 2 OH⁻(aq)

I                                 0                  0

C                              +x               +2x

E                                x                 2x

Step 3: Write the expression for the solubility product constant (Ksp)

The solubility product constant is equal to the product of the concentrations of the products raised to their stoichiometric coefficients.

Ksp = [Ca²⁺] × [OH⁻]² = x × (2x²) = x × 4x² = 4x³

hope you got the answer

they are made of gases.

they have a spherical shape.

they make energy through fusion.
