Question

Copper (I) ions in aqueous solution react with NH3 to form [Cu(NH3)2]+. The Kf of that complex is 6.3 x 1010. Calculate the solubility of CuBr in 0.50 M NH3. The Ksp of CuBr is 6.3 x 10-9

Answer 1

Given the solubility product of CuBr is 6.3 * 10^-9

Formation constant for the formation of complex [Cu(NH3)2]^+ is 6.3*10^10
