Question

The salt which does not react with acid or base is:
A) Sodium hydroxide
B) Sulphuric acid
C) Sodium chloride
D) Sodium acetate

Answer 1

Hint: We know an acid and base under neutralization reaction reacts to form a salt. The stronger the acid and base, the more neutral is the salt formed.

Complete answer:
> Some of the strong acids are (HCl, ${H_2}S{O_4}, HN{O_3}$ etc.) and some of the strong bases are (LiOH, NaOH, KOH etc). A salt formed by the reaction of strong acid and strong base is highly neutral in nature and will further not react with any acid or base . Now let’s analyze the acid and base of every salt .
> Sodium hydroxide is not a salt it is an Arrhenius base that dissociates into sodium and hydroxides ions in water thereby releasing (OH) anions.
> Sulphuric acid is a strong acid that will react with a base leading to neutralization reaction. > Sodium chloride (NaCl) is a highly neutral salt and will not react with any acid or base as it is formed by sodium hydroxide and hydrochloric acid both of which are quite strong base and acid respectively.

$NaOH(aq) + HCl(aq) \to NaCl(aq) + {H_2}O(l)$

> Sodium acetate is a basic salt and will react with acid as it is formed by a strong base (sodium hydroxide) and weak acid (acetic acid).

$NaOH + C{H_3}COOH \to C{H_3}COONa + {H_2}O$

Hence the correct option is option C. Sodium chloride is a highly neutral salt and will not react with any acid or base.

Note: Strong acid +strong base gives a neutral salt of ph 7.
Strong acid +weak base gives an acidic salt that reacts with base.
Strong base + weak acid gives a basic salt that reacts with acid.
Weak base +weak acid gives a weak salt that hydrolyzes quite easily.
