Question

Someone help me pls thank you

Answer 1

The solubilty product (Ksp) of PbCl₂ : Ksp = [Pb²⁺][Cl⁻]²

Further explanation

Given

PbCl₂ compound

Required

The solubilty product (Ksp)

Solution

Ksp is the product of ions in an equilibrium saturated state

For reaction :

AₓBₐ (s) ⇔ aAᵃ⁺ (aq) + b Bᵇ⁻ (aq)

Can be formulated :

Ksp = [Aᵃ⁺] ᵃ [Bᵇ⁻] ᵇ

For PbCl₂ :

PbCl₂(s)⇔Pb²⁺(aq) + 2Cl⁻(aq)

Ksp = [Pb²⁺][Cl⁻]²
