A student says that an antacid increases acidity in the stomach. What is the correct correction to this statement?

Answer and explanation

Correct answer: An antacid neutralises excess hydrochloric acid.

Antacids contain mild bases, such as suitable hydroxide, carbonate, or bicarbonate compounds. These bases react with excess hydrochloric acid in the stomach, reducing the concentration of hydrogen ions and relieving acidity. The process is neutralisation, not acid production or conversion into a stronger acid. Cooling food is unrelated to the chemical action. Therefore, option A correctly revises the statement.
