Define the term enthalpy of neutralization. Write the ionic equation for neutralization. Write the equation for the reaction between propanoic acid and ethanol

The ionic equation for neutralization (specifically for a strong acid and a strong base) is:

$$\text{H}^{+}(\text{aq}) + \text{OH}^{-}(\text{aq}) \longrightarrow \text{H}_2\text{O}(\text{l})$$

The equation for the reaction between propanoic acid and ethanol (an esterification reaction) is:

$$\text{CH}_3\text{CH}_2\text{COOH}(\text{l}) + \text{CH}_3\text{CH}_2\text{OH}(\text{l}) \rightleftharpoons \text{CH}_3\text{CH}_2\text{COOCH}_2\text{CH}_3(\text{l}) + \text{H}_2\text{O}(\text{l})$$

This reaction typically requires an acid catalyst (like concentrated H₂SO₄) and heat.
