Question

Help, please!!

Consider the two compounds, Agl(s) and CuCO3(s). One of the these is more soluble in acid solution than in water.which one and in a brief statement explain why?

Answer 1

CuCO₃ ( s ) is more soluble in acid solution than water .

Supporting reaction in water and acid solution are given as following .since equilibrium constant of second reaction is greater in case of acid solution ; CuCO3 ( s ) has to solubilise more in case of acidic solution.

For carbonic acid K_a1 is order of 10^–7 and K_a2 is order of 10^{–11.
