## Brønsted-Lowry Acids and Bases in Net Ionic Equations

### Instructions
Use the references to access important values if needed for this question.

### Task
Identify whether each species functions as a Brønsted-Lowry acid or a Brønsted-Lowry base in this net ionic equation:

\[ \text{CN}^- + \text{H}_3\text{PO}_4 (\text{aq}) \rightarrow \text{HCN} (\text{aq}) + \text{H}_2\text{PO}_4^- \]

- **CN⁻**
  - **Brønsted-Lowry**: [acid/base] (select the correct option)

- **H₃PO₄ (aq)**
  - **Brønsted-Lowry**: [acid/base] (select the correct option)

- **HCN (aq)**
  - **Brønsted-Lowry**: [acid/base] (select the correct option)

- **H₂PO₄⁻**
  - **Brønsted-Lowry**: [acid/base] (select the correct option)

### Questions
In this reaction:

1. The formula for the conjugate ____ of CN⁻ is [___________].
2. The formula for the conjugate ____ of H₃PO₄ is [___________].

### Learning Goals
