Which statement describes a neutralization reaction?

• A. Oxidation-Reduction
• B. Acid + Base -> Salt + Water
• C. Precipitation
• D. Combustion

Answer: (B)

Neutralization is an acid–base reaction where an acid reacts with a base to form a salt and water. In water, acids provide hydrogen ions (H+), bases provide hydroxide ions (OH−), and when they combine, the H+ and OH− form H2O while the remaining ions make a salt. For example, HCl reacting with NaOH yields NaCl and H2O. This specific outcome—salt plus water—is what defines a neutralization reaction. Other options describe different types of chemical changes: oxidation–reduction involves electron transfer, precipitation is the formation of a solid from ions in solution, and combustion is burning with oxygen.
