Answer:
Acid: An acid is a compound which when dissolved in water yields - hydronium ions {H₃O⁺} as the only positively charged ions.
Example : HCl + H₂O → H₃O⁺ + CL⁻.
Bases : A base is a compound which reacts with hydronium ions {H₃O⁺} of an acid - to give salt and water only.
Example : CuO + 2HCl → CuCl₂ + H₂O
Salts : A salt is a compound formed by partial or complete replacement
- of a replaceable hydronium ion of an acid
- metallic ion or an ammonium ion.
NaOH + H₂SO₄ → NaHSO₄ + H₂O →→→→→→→→→→ Partial replacement
