**Understanding Brønsted-Lowry Acids in Reactions**

**Question:** In this reaction, which is the Brønsted-Lowry acid?

**Diagram Explanation:**

The diagram illustrates a chemical reaction sequence, showcasing the interaction between different molecules and ions. The goal is to identify which species acts as a Brønsted-Lowry acid by donating a proton (H⁺).

1. **Starting Materials:**
   - **A**: Depicts the iodine ion (I⁻) approaching the reaction.
   
2. **Intermediate Steps:**
   - **B**: Shows water (H₂O) donating a proton to an iodine ion, forming a hydronium ion (H₃O⁺) and iodide ion (I⁻).
   - **C**: Illustrates the iodine ion (I⁻) abstracting a hydrogen from the hydronium ion (H₃O⁺), further progressing the reaction.
   - **D**: Focuses on the transfer of the proton from H₃O⁺ to I⁻, forming hydroxide (OH⁻) and hydronium (HI).

3. **Final Products:**
   - Hydroxide (OH⁻) and hydronium iodide (HI) are formed as the end products of this reaction sequence.

**Conclusion:**
- In the context of the Brønsted-Lowry theory, a Brønsted-Lowry acid is defined as a species that donates a proton. In this reaction, the water molecule (H₂O) acts as the Brønsted-Lowry acid. It donates a proton to form the hydronium ion (H₃O⁺).

Understanding this concept is crucial for analyzing acid-base reactions, as it helps identify the role of each reactant in proton transfer processes.
