### In the lessons

In science lessons antacids show neutralisation: a base (alkali) reacts with acid and makes it less acidic. Many antacids contain calcium carbonate or magnesium hydroxide. In everyday life adults take them after spicy or big meals. Safety: only take medicine with an adult's permission.
