Question

What are the strong acids and weak acids? Give an example of each.

Answer 1

Strong acids:

• The acids that dissociate almost completely into ${\mathrm{H}}^{+}$ ions in an aqueous solution are strong acids.
• These are highly corrosive in nature.

Examples:

• Hydrochloric acid $\left(\mathrm{HCl}\right)$ and Sulfuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$

Weak acids:

• The acids that dissociate partially into ${\mathrm{H}}^{+}$ions in an aqueous solution are weak acids.
• These are less corrosive in nature.

Examples:

• Acetic acid $\left({\mathrm{CH}}_3\mathrm{COOH}\right)$and Formic acid $\left(\mathrm{HCOOH}\right)$
