Chem112 lecture 29 more solubility calculations. 2- (aq) and ksp = 1. 3 x 10-7. We must do this because this is the k we need to work with, and we cannot use the k from the hydrolysis reaction: now add these two reactions together (aq) Co3 (aq) hco3 (aq) + h3o+ (aq) + co3. 2- (aq) + h2o(l: the overall reaction. The knet = 2. 3 x 103 (aq) ni2+ (aq) + hco3 (aq) + h2o(l) 2: b. k = kw, c. k = 1/kw, d. k = kw, the answer is a. Solubility and complex ions: the formation of a complex ion can be used to increase the solubiltuy of an. Insoluble compound: example, consider zinc cyanide, zn(cn)2, where the ksp = 8. 0 x 10-12. The zinc ion will also form a complex ion with hydroxide ions. Write an equation to show why the solubility of zn(cn)2 increases in the presence of oh-, and calculate the knet for this reaction.
