A dry pellet of a common base B, when kept in the open absorbs moisture and turns sticky. The compound is also a by-product of the chloralkali 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.

Sodium hydroxide is a byproduct of chloralkali process. When it is kept in open, it absorbs moisture and turns sticky. 

If NaOH is treated with acidic oxide (carbon dioxide), it gives Sodium carbonate.
$2NaOH+ CO_2 →Na_2CO_3+ H_2O$

 Since this reaction is between a basic compound and an acidic compound, hence it is a neutralization reaction.
B is sodium hydroxide.
