Question

Explain the following chemical properties of acid with the help of balanced chemical equation only. (1)when an acid reacts with a metal carbonate. (2)when an acid reacts with a metal bicarbonate. (3)when an acid reacts with a metal oxide.

Answer 1

Metal carbonate+acid=salt+water
Metal oxide+acid=salt +water
metal bicarbonate+acid=salt+water+co2

Answer 2

Answer:

The balanced chemical equation for given questions are following:

Explanation:

1. When an acid reacts with a metal carbonate: The acid reacts with the metal carbonate or metal bicarbonate to form carbon dioxide with the corresponding metal salt and water.

⇒ $Na_{2} CO_{3} + 2HCl$ → $2NaCl_{} +$ $H_{2}O + CO_{2}$

2. When an acid reacts with metal bicarbonate: The acid reacts with the metal carbonate or metal bicarbonate to form carbon dioxide with the corresponding metal salt and water.

⇒ $NaHCO_{2} + HCl$→ $NaCl_{} +$$H_{2}O + CO_{2}$

3. When an acid reacts with a metal oxide: When an acid reacts with a metal oxide, salt and water are formed. Metal oxides are bases because they neutralize acids.

⇒ $Na_{2}O + 2HCl$ → $2NaCl_{} + H_{2}O$
