Question
Consider the solubility of ZnCO3 in aqueous solution. For each experimental condition below, indicate whether solubility will increase, decrease or have no change.
Experimental condition
Change in solubility vs. pure water
Add NaCl until I = 0.10 M
Add HCl until pH ~ 2
Add NaOH until pH ~ 10
Add EDTA
Add ZnCl2
Increase the temperature
