Question

Which of the following equations represents the relation between solubility (mol L⁻¹) and solubility product for the salt B₂A?

विकल्प

• S = `(K_(sp)/4)^(1/3)`

• S = `(4 K_(sp))^(1/3)`

• S = `(K_(sp)/3)^(1/3)`

• S = `(3 K_(sp))^(1/3)`

Answer 1

`bb(S = (K_(sp)/4)^(1/3))`

Explanation:

\[\ce{B2A <=> 2B+ + A^{2-}}\]

K_sp = [B⁺]² [A²⁻]

K_sp = (1)¹ (2)² (S)² (S)

K_sp = 4 S³

S = `root(3) (K_(sp)/4)`

S = `(K_(sp)/4)^(1/3)`
