Which among the following pairs of acid and base are weak, respectively?

  1. HCOOH and NH4OH
  2. HCl and NaOH
  3. CH3COOH and KOH
  4. HClO4 and CsOH

hintHint:

HCOOH and NH4OH

The correct answer is: HCOOH and NH4OH


    A strong acid is one that completely dissociates into its constituting ions in an aqueous solution. A weak acid doesn't completely dissociate into its ions.
    A strong base is one that completely dissociates into its constituting ions in an aqueous solution. A weak base doesn't completely dissociate into its ions.
    HCOOH and NH4OH are pairs of acid and base are weak, respectively.
