A student has 10 mL of a solution that might contain any or all of the following cations at 0.01 M concentrations: Mn²⁺, Ba²⁺, Ag⁺, and Cu²⁺. Addition of 10 mL of 1 M HCl causes a precipitate to form. After the precipitate is filtered off, 1 M H₂SO₄ is added to the filtrate and another precipitate forms. What is the second precipitate?
