C1.10 Indigestion

  • Your stomach produces hydrochloric acid which kills bacteria on your food.
  • The stomach digests your food. (Digests-Breaking down food.)
  • Sometimes the stomach produces too much acids,which causesindigestion.
  • The reaction between an acid and a base is called a neutralisation reaction: Acid + Base ==> Salt + Water
  • ✱ Some bases are soluble, only a base dissolved in water is called an alkaline.
  • If an Antacid contains a carbonate Carbon dioxide (CO2) is produced. eg. Acid + Base ==> Salt + Water + Carbon Dioxide   
  • Eg. HCL +CaCO3 ==> Cacl2 + H20 + CO2
  • Acid and Alkalines are descirbed using a pH Scale.
  • Liquids can be investigated using an indicator. eg. Universal indicator turns red for acids, green for neutral and purple foralkalines.
  • Litmus is another indicator.
