base are bitter in taste

Answer 2

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
