• Antacids work by counteracting (neutralising) the acid in your stomach.
• They do this because the chemicals in antacids are bases (alkalis) which are the opposite of acids.
• A reaction between an acid and base is called neutralisation.
• This neutralisation makes the stomach contents less corrosive.
