![**Problem: Hydronium Ion Concentration Calculation**
What is the hydronium ion concentration of a 0.200 M hypochlorous acid solution with \( K_a = 3.5 \times 10^{-8} \)? The equation for the dissociation of hypochlorous acid is:
\[ \text{HOCl(aq)} + \text{H}_2\text{O(l)} \rightleftharpoons \text{H}_3\text{O}^+(\text{aq}) + \text{OCl}^-(\text{aq}) \]
**Options:**
- \( \bigcirc \) \( 3.7 \times 10^{-5} \) M
- \( \bigcirc \) \( 8.4 \times 10^{-4} \) M
- \( \bigcirc \) \( 8.4 \times 10^{-5} \) M
- \( \bigcirc \) \( 1.9 \times 10^{-4} \) M
**Instructions:**
Calculate the hydronium ion concentration using the given \( K_a \) value and the initial concentration of hypochlorous acid. Select the correct answer.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd452bd8c-7554-4806-a6d8-accf0f380aea%2Feae50661-0a8a-4288-8229-40913e7e6491%2Ffp55rk_processed.jpeg&w=3840&q=75)
