Problem: Copper(l) ions in aqueous solution react with NH3(ag) according toCu+(aq) + 2NH3(aq) → Cu(NH3)2+(aq)           Kf = 6.3 x 1010Calculate the solubility (in g • L-1) of CuBr(s) (Ksp = 6.3 x 10-9) in 0.88 M NH3(aq).

FREE Expert Solution

CuBr (s) ⇌ Cu+ (aq) + Br- (aq)


Ksp =productsreactants=[Cu+][Br-]


Cu+ (aq) + 2 NH3 (aq) → Cu(NH3)2 (aq)


Kf =productsreactants=[CuNH32][Cu+][NH3]2


CuBr(s) + 2 NH3 (aq) ⇌ Cu(NH3)2 (aq) + Br- (aq)


K = productsreactants = [Cu(NH3)2][Br-][NH3]2
