Which equation represents a neutralisation reaction?

Which equation represents a neutralisation reaction?

• A. Acid + Base = Salt + Water
• B. Salt + Water = Acid + Base
• C. Acid + Salt = Base + Water
• D. Base + Water = Salt + Acid

Answer: (A)

Neutralization is when an acid reacts with a base to form a salt and water. The hydrogen ions from the acid combine with hydroxide ions from the base to make water, while the remaining ions form a salt. The equation that shows acid plus base giving salt plus water matches this process directly. For example, an acid like HCl reacting with a base like NaOH yields NaCl (salt) and H2O (water). The other options don’t depict this acid–base pairing producing water and a salt, so they don’t represent neutralization.
