23. A neutralization reaction between an acid and a base always produces

Answer 1

D.
 reaction in which acidity or alkalinity is removed is called neutralisation. A neutralisation involving an acid and a base (or alkali) always produces salt and water.

acid + base > salt + water

Answer 2

Answer: d. salt and water.

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

A neutralization reaction is a double displacement reaction in which an acid reacts with base to produce salt and water.

Example:

$2NaOH(aq)+H_2CO_3(aq)\rightarrow Na_2CO_3(aq)+2H_2O(l)$
