Some common weak acids are Formic Acid (HCOOH), Acetic Acid (CH3COOH), Trichloroacetic acid (CCl3COOH), Hydrofluoric acid (HF), and Hydrocyanic acid (HCN).
Common weak bases include ammonia (NH3), trimethyl ammonia (N(CH3)3), pyridine (C5H5N), and ammonium hydroxide (NH4OH).
The few names of strong and weak bases are:-
WEAK BASES:- Ammonium hydroxide, aluminium hydroxide.
STRONG BASES:- Calcium hydroxide, sodium hydroxide, potassium hydroxide and magnesium hydroxide.
Weak acids include acetic acid, citric acid, and carbonic acid. Weak bases include ammonia, methylamine, and pyridine.

No, the conjugate of a strong base is a weak acid. The conjugate base of a strong acid is weak, while the conjugate acid of a strong base is weak.
b) The conjugate acid of a weak base is a weak acid. When a base accepts a proton to form its conjugate acid, it tends to be a weak acid because it does not easily donate a proton back. This relationship is governed by the principles of acid-base equilibrium.
HCOO- is the conjugate base of formic acid (HCOOH) which is a weak acid. Therefore, HCOO- is a weak base.
A solution containing a weak acid and its salt will act as a buffer, maintaining the pH by neutralizing added acid or base. Similarly, a weak base and its salt can also function as a buffer. Weak acid-weak base buffer systems are commonly used in chemical laboratories and biological systems to control pH fluctuations.
No, HNO2 is a weak acid, not a weak base. It is a weak acid because it only partially ionizes in water to release H+ ions.
