Question

Hi! Thank you very much for taking the time to help me with this question! It says you need the ksp data on aleks but I do not believe you actually need it. In case you find yourself in fact needing it, I have provided the values below. Thanks!

ksp CaCO3: 1.4×10⁻¹⁰

ksp Ba(OH)2: Not given

ksp AgCl: 1.77×10⁻¹⁰

·if the so bility does change, pick the i For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with at which you'd expect the highest solubility. You'll find Ksp data in the ALEKS Data tab. Does solubility highest solubility compound change with pH? pH pH 5 Caco, yes CaCO3 no o yes Ba (OH)2 no yes AgCl O no

Answer 1

CaCO3 is a basic salt, hence on increasing pH, OH- ions increase in solution which by le Chaterliers principle will cause solubility equilibrium to shift to left, hence solubility will decrease. Lower pH will have higher solubility hence answer is pH 4.

Barium hydroxide will again have a higher solubility in acidic pH hence answer is pH 4

AgCl solubility is not much affected by change in pH. Hence answer is No.
