Determine the effect of the addition of a strong acid Ho on

Determine the effect of the addition of a strong acid (H,o\') on the solubility for each of the following compounds: ZncO Sns PbBr Cul Chrose... no effect increases solubility decreases solubility Choose... Ni (Po2 Choose..

Solution

ZnCO₃ ------> CO₃^2- will react to form weak acid H₂CO₃ so solubility INCREASES

SnS ------> S^2- will react to form weak acid H₂Sso solubility INCREASES

PbBr₂ -------> Br^- will react to form HBr but it is a strong acid so solubility NO EFFECT

CuI ------> I^- will react to form HI but it is also a strong acid so solubility NO EFFECT

Ni₃(PO₄)₂-------> PO₄^3- will react to form H₃PO₄ but it is a strong acid so  solubility NO EFFECT
