Question

which of the following Ksp is more likely to favor products?

1) aluminum hydroxide ; Ksp 3x10^-34

or

2) barium bromate Ba(BrO3)2 , Ksp 2.43x10^-4

Answer 1

#2 barium bromate would favor the products

Aluminum hydroxid = Al(OH)₃

Al(OH)₃(s) <==> Al³⁺(aq) + 3OH^-(aq)

Ksp = 3x10^-34 = [Al³⁺][OH-]³ = (x)(3x)³ = 27x⁴

x = molar solubility = 1.83x10^-9 M

Ba(BrO₃)₂(s) <==> Ba²⁺(aq) + 2BrO₃^-(aq)

Ksp = 2.43x10^-4 = [Ba²⁺][BrO₃^-]² = (x)(2x)² = 4x³

x = molar solubility = 3.93x10^-2 M
