**Chemical Reaction and Calculations for Barium Sulfate Precipitation**

A student mixes 50.0 mL of 1.00 M Ba(OH)₂ with 72.5 mL of 0.375 M H₂SO₄.

1. **Calculate the mass of BaSO₄ formed.**

   Enter your answer in the box provided: _____ g

2. **Calculate the pH of the mixed solution.**

   Enter your answer in the box provided: _____

**Explanation:**

In this reaction, Barium hydroxide [Ba(OH)₂] reacts with sulfuric acid [H₂SO₄] to form barium sulfate [BaSO₄] and water [H₂O] as follows:

\[ \text{Ba(OH)}_2 \, + \, \text{H}_2\text{SO}_4 \rightarrow \text{BaSO}_4 \, + \, 2\text{H}_2\text{O} \]

**Instructions for Calculation:**

- Determine the limiting reactant.
- Calculate the mass of BaSO₄ precipitated using stoichiometry.
- Use the concentrations of the remaining [H⁺] or [OH⁻] ions to calculate the pH of the solution after reaction.
