Question
Which among the following pairs of acid and base are weak, respectively?
- HCOOH and NH4OH
- HCl and NaOH
- CH3COOH and KOH
- HClO4 and CsOH
Hint:
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.
