When using H₂SO₄ in aqueous reactions, many problems are presented or solved by assuming both of the hydrogen ions to be strongly ionized, as if they were both strong acid ionization processes. At the same time, the second H⁺ only weakly ionizes in aqueous solution.

1. Write molecular, complete ionic, and net ionic equations for the reaction between sulfuric acid and barium hydroxide (a strong base) using the following assumptions:

a. Both hydrogen ions of H₂SO₄ are assumed to ionize 100% like strong acids.

b. Only the first hydrogen ion of H₂SO₄ is 100% ionized, and the second is weakly ionized.

2. Write molecular, complete ionic, and net ionic equations for the reaction between sulfuric acid and sodium acetate, a weakly basic salt, using the following assumptions:

c. Both hydrogen ions of H₂SO₄ are assumed to ionize 100% like strong acids.

d. Only the first hydrogen ion of H₂SO₄ is 100% ionized, and the second is weakly ionized.
