Question

Give an example of a weak acid?

Answer 1

Weak acid:

• The acids which don't completely dissociate or partially dissociate into ions in the aqueous solution are called weak acids.
• Depending on its strength to dissociate, the acids dissociating more are strong whereas the ones that dissociate very less are called weak acids.
• The majority of the acids are weak acids. Also, most organic acids are weak.
• In the aqueous solution, the weak acid is always in equilibrium with its constituent ions.
• Examples of weak acids are formic acid$\left(\mathrm{HCOOH}\right)$, acetic acid$\left({\mathrm{CH}}_3\mathrm{COOH}\right)$, phosphoric acid$\left({\mathrm{H}}_3{\mathrm{PO}}_4\right)$, etc.

Hence, the example of a weak acid is acetic acid$\left({\mathrm{CH}}_3\mathrm{COOH}\right)$.
