Question: 3 assuming the activity of cu2aq is controlled by equilibrium...

Question details

3. Assuming the activity of Cu2+(aq) is controlled by equilibrium with the solid phase

Cu(OH)2(s):

(i) Write the balanced chemical reaction.

(ii) Now write a second balanced chemical reaction for the formation of an aqueous complex

between Cu2+ (aq) and a Cl- (aq) ligand.

(iii) Given these two reactions, does the presence of the complexing ligand in solution affect the

free aquo metal concentration? Explain.

(iii) Does the presence of metal complexing ligands affect the total metal concentration in

equilibrium with a solid phase? Explain.
