Question

Identify the odd one out and justify sodium nitrate,sodium carbonate, sodium sulphate,sodium chloride

Answer 1

Answer:

Sodium Carbonate is the odd one out.

This is because, all the other salts are prepared from strong bases and strong acids therefore acting as neutral salts. But Sodium Carbonate is formed from Strong base and a Weak acid. Due to this it acts as a Basic Salt. Therefore it is the odd one out.

• Sodium Nitrate = Nitric Acid + Sodium Hydroxide
• Sodium Sulphate = Sulphuric Acid + Sodium Hydroxide
• Sodium Carbonate = Carbonic Acid + Sodium Hydroxide
• Sodium Chloride = Hydrochloric Acid + Sodium Hydroxide

Here, except Carbonic acid all other acids are strong.

Answer 2

Answer:

Sodium carbonate is ur answer

Explanation:

Sodium carbonate is odd because the solutions of sodium nitrate, sodium sulphate and sodium chloride are neutral. But the solution of sodium carbonate is BASIC.
