Question

A dry pallet of common base X when kept in open air absorbs moisture and turns sticky. the compound is also a by product of chlor alkali process. identify X what type of reaction occurs when X is treated with strong acid? write a balanced chemical equation for such reaction.

Answer 1

(i) B is sodium hydroxide (NaOH).
(ii) Neutralisation reaction occurs when B is treated with an acidic oxide.
iii) NaOH + HCl ▪▪▪▪▪▪▪▪▪> NaCl +
$H_{2}O$

Answer 2

Answer: 1) The compound X is $NaOH$

2. Neutralization occurs when base combines an acid to give salt and water. $NaOH+HCl\rightarrow NaCl+H_2O$

Explanation: Dry pellets of $NaOH$ are hygroscopic in nature i.e they absorb moisture when placed in air.

Chlor alkali process is called so because when electricity is passed through an aqueous solution of sodium chloride, chlorine gas is produced at anode and hydrogen gas at the cathode.The remaining $Na^+$ and $OH^-$ ions combine to form NaOH.

When acid and base combines , neutralization reaction takes place resulting in the formation of salt and water.

The chemical equation representing the reaction of sodium hydroxide with a strong acid hydrochloric acid is:

$NaOH+HCl\rightarrow NaCl+H_2O$
