Question

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.

Accepted Answer

Sodium hydroxide $(NaOH)$ is common base and is hygroscopic, that is, it absorbs moisture from the atmosphere and becomes sticky.

Thus, base $B$ is $NaOH$ (sodium hydroxide). It is the product of chlor-alkali process along with the evolution of hydrogen and chlorine gas.

The acidic oxide reacts with base to give salt and water.

If ${CO}_{2}$ is the acidic oxide taken, then the following reaction takes place with 'B'.

$\begin{matrix} \underset{\begin{matrix} Sodium \\ \begin{matrix} hydroxide \\ (B) \end{matrix} \end{matrix}}{2 NaOH} + {CO}_{2} & \to \underset{\begin{matrix} Sodium \\ Carbonate \end{matrix}}{{Na}_{2} {CO}_{3}} & + H_{2} O \end{matrix}$

Such reaction is called a neutralisation reaction.

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.
