C). CaCO3
D). AgI

Help please!:) thAnks

    An acid, at least for this discussion contains H^+. So what will that combine with in a salt? It will combine with the anion, of course. So if the anion will react with the H^+, then it will be more soluble in an acid.
    Hg2Br2 will give HBr but that is a strong acid and will ionize 100%; no reaction. solubility not increased.

    Mg(OH)2. Add acid, it reacts with the OH part to make water, solubility increased by adding acid.

    I'll leave the other two for you.
