- Ammonium Hydroxide (NH4OH) is a basic solution which does not contain a metallic element.
- Sodium acetate (CH3COONa) is a normal salt of sodium formed from acetic acid.
- Ammonium hydroxide (NH4OH) is a base which reacts with an acid to give a salt which on hydrolysis gives a slightly acidic solution.
- Hydrogen ion (H+) is an ion which combines with a polar covalent molecule to form an ammonium ion.
- Aluminium chloride (AlCl3) is a soluble salt formed by direct combination between a light metal & a greenish yellow gas where, light metal is Al and greenish yellow gas is Cl.
