Indigestion

Indigestion

1. Stomach Acid

   • Hydrochloric acid
   • Kills bacteria in food
   • Helps digestion, as some enzymes that break down our food only work in acidic conditions.
   • Sometimes the stomach produces too much acid, causing pain called indigestion.
   • Indigestion remedies contain antacids
     • Neutralises excess stomach acid.
       • Neutral liquids are neither acids or alkalis.
       • Antacids
         • Contain substances called bases.
           • Bases react with acids and neutralise them.
             • Some bases are soluble
             • A base dissolved in water is called an alkali.
           • acid + base -> salt + water
             • Neutral liquids have a pH of 7
               • Acids have a pH less than 7
                 • When an indigestion remedy is added to an acid, it'll neutralise some of the acid and the pH will increase.
