Question

Which compound is more soluble in an acidic solution than in a neutral solution?

a.AgCl
b.BaCO3
c.PbI2
d.HgBr2

Answer 1

Hey there!:

More soluble in acidic solution than in neutral solution :

* Here the conjugate acids of AgCl , HgBr2 , and Pbl2 are HCl , HBr and HI which are strong , so these are slightly soluble in acidic solution .

* But the conjugate acid of BaCO3 is H2CO3 wich is weak acid, more soluble in acidic solution than in neutral solution.

Hope this helps!
