# Bicarbonate ions react with water in an aqueous solution according to the equilibrium represented below:

\[ \text{HCO}_3^-\text{(aq)} + \text{H}_2\text{O(l)} \rightleftharpoons \text{CO}_3^{2-}\text{(aq)} + \text{H}_3\text{O}^+\text{(aq)} \]

Which of the following correctly identifies a Brønsted-Lowry conjugate acid-base pair in this reaction?

Bicarbonate ions react with water in an aqueous solution according to the equilibrium represented below:

\[ \text{HCO}_3^-\text{(aq)} + \text{H}_2\text{O(l)} \rightleftharpoons \text{CO}_3^{2-}\text{(aq)} + \text{H}_3\text{O}^+\text{(aq)} \]

Which of the following correctly identifies a Brønsted-Lowry conjugate acid-base pair in this reaction?

- **A.** \(\text{H}_3\text{O}^+\text{(aq)}\) and \(\text{H}_2\text{O(l)}\)
- **B.** \(\text{HCO}_3^-\text{(aq)}\) and \(\text{H}_2\text{O(l)}\)
- **C.** \(\text{CO}_3^{2-}\text{(aq)}\) and \(\text{H}_3\text{O}^+\text{(aq)}\)
- **D.** \(\text{HCO}_3^-\text{(aq)}\) and \(\text{H}_3\text{O}^+\text{(aq)}\)
