Of the slightly soluble solids BaF2, CaCO3, and Mg(OH)2, which will be more soluble in 1 M H30+ than in water?
A. Only CaCO3
B. Only Mg(OH)2
C. Only BaF2
D. CaCO3 and BaF2
E. All three
Homework Answers
The answer is all three. All the three given compounds are basic. And the given solvent has H3O+ ions which makes the solvent acidic. So, all the three compounds dissolve more than in water.
