Answer 1

For each of the following compounds, decide whether the compound's solubility in aq at which you'd expect the highest solubility. You'll find K, data in the ALEKS Data ta compound Does solubility change with pH? highest solubility pH = 6 | pH = 4 pH = 1. yes Ba(OH)2 O O no * 0:00 MgCl2 yes no yes CaCO3 Опо x ?

Explanation :

Ba(OH)2   -----------> Ba2+   +   2 OH-

here OH- ions react with H+ ions . so here solubility increases at low pH .

MgCl2 is salt of strong acid and strong base . so pH does not effect the solubility

CaCO3 ---------> Ca2+     +   CO32-

here CO32- react with H+ ions . so here solubility increases at low pH .
