Question

Mixing an acid and base results in an exothermic reaction.

• A. True
• B. False

Answer 1

The correct option is A True

1. An exothermic reaction is a chemical or physical reaction that releases heat.
2. When an acid readily combines with a base, giving out heat energy is called an exothermic reaction .
3. The reaction between an acid and a base, which results in the formation of salt and water is called a neutralization reaction, which is exothermic in nature. $\mathrm{Acid}+\mathrm{Base}\to \mathrm{Salt}+\mathrm{Water}+\mathrm{Heat}$
4. For example: $$\begin{gathered} \mathrm{HCl}\left(\mathrm{aq}\right)+\mathrm{NaOH}\left(\mathrm{aq}\right)\to \mathrm{NaCl}\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+\mathrm{Heat} \\ (\mathrm{Hydrochloric}\mathrm{acid})(\mathrm{Sodium}\mathrm{hydroxide})(\mathrm{Sodium}\mathrm{chloride})\left(\mathrm{Water}\right) \end{gathered}$$

Therefore, the given statement- Mixing an acid and base results in an exothermic reaction is true.
