You are given an aqueous solution and are asked to analyze it for the presence (or absence) of Ag+(aq), Ca2+(aq), and/or Hg2+(aq
pantera1 [17]

Answer:

(c) only Ca2+(aq) and Hg2+(aq)

Explanation:

  • In the first step, hydrochloric acid (HCl) is added to the solution. In this case the equilibrium that could take place is:

Ag⁺(aq) + Cl⁻(aq) ↔ AgCl(s)

But no precipitate was formed, so Ag⁺(aq) is absent.

  • By adding H₂SO₄(aq) the next equilibrium that could take place is:

Ca⁺²(aq) + SO₄⁻²(aq)  ↔ CaSO₄(s)

A white precipitate was formed, so Ca⁺² is present in the solution.

  • The following could take place after adding H₂S(aq):

Hg²⁺(aq) + S⁻² ↔ HgS(s)

A black precipitate formed, so Hg⁺² is present as well.
