Transcribed Image Text:Propose two methods you might use to dissolve a precipitate of solid CuCO3 in aqueous solution.
First write the chemical equation for the saturated solution equilibrium of CuCO3.
Expert Solution
Step 1
two methods for dissolving CuC3 in aqueous solution
CuCO3(s) <-> Cu2+ (aq) + CO32- (aq)
then, add H+ so :
CO32 + H+ <-> HCO3- formation
then, this favours Cu²+ in solution, i.e. dissolving of CuCO3
ALSO
addtion of base:
Cu+2 + 2OH-(aq) --> Cu(OH)2(s)
so, shift goes once again toward dissolution of CuCO3
