Question

You have hydrochloric acid in a beaker and you want to perform the experiment of neutralization, so which among the following will you use?

• A. $NaOH$
• B. $HN{O}_3$
• C. $H_{2}S{O}_4$
• D. $Ca(OH{)}_2$

Answer 1

Answer: (A), (D)

The correct options are
A

$NaOH$

D

$Ca(OH{)}_2$

An acid reacts with a base to neutralize its effect. Hydrochloric acid will react with a base to form salt and water respectively. Here, Sodium hydroxide and calcium hydroxide are bases so HCl will react with both to form salt and water.

HCl + NaOH $\to$ NaCl + H₂O
$Ca(OH{)}_2$ + $2HCl$ $\to$ $CaC{l}_2$ + $2H_{2}O$

Sodium chloride and water are formed.

Two acids do not react so HCl will not react with sulphuric acid and nitric acid.
