Question

Write any three chemical properties of acids.

Answer 1

Acids: The compounds which produce hydrogen $\left(H^{+}\right)$ions when dissolved in water are known as acids.

Chemical properties of acids:

$1.$Acids react with metals to form salts and release hydrogen gas.

$2.$ Acids react with bases to form salts and water, which is also known as a neutralization reaction.

Example of a Neutralization reaction:

$$\begin{gathered} \mathrm{HCl}+\mathrm{NaOH}\to \mathrm{NaCl}+{\mathrm{H}}_2\mathrm{O} \\ \left(\mathrm{Hydrochloric} \\ \mathrm{acid}\right)\left(\mathrm{Sodium} \\ \mathrm{hydroxide}\right)\left(\mathrm{Sodium} \\ \mathrm{chloride}\right)\left(\mathrm{Water}\right) \end{gathered}$$

$3.$Acids have a pH value of less than $7.$
