A dry pellet of a common base B, when kept in open absorbs moisture and turns sticky. The compound is also a by-product of Chlor-alkali process. Identify B. What type of reaction occurs when B is treated with an acidic oxide? Write a balanced chemical equation for one such solution.

‘B’ is NaOH. It absorbs moisture from atmosphere because it is hygroscopic in nature. It is obtained by product of chlor-alkali process.

2NaCl + 2H₂O → 2NaOH + Cl₂(g)(At anode) + H₂(g)

2NaOH('B') + CO₂→ Na₂CO₃ + H₂O

‘B’ reacts with acidic oxide CO₂ to form salt and water. This reaction is called neutralisation reaction.
