Which of the following represents a neutralization reaction
A. Sodium hydroxide + hydrochloric acid> sodium chloride+ water
B. Calcium oxide+ water>calcium hydroxide
C. Carbon + oxygen> carbon dioxide+water
D. Sodium+ chlorine> Sodium chloride
A. Sodium hydroxide + hydrochloric acid > sodium chloride + water
The correct answer is option A.
A neutralization reaction occurs when an acid reacts with a base to form a salt and water. In this reaction, sodium hydroxide (a base) reacts with hydrochloric acid (an acid) to produce sodium chloride (a salt) and water.
