Topics 3,4,5 - Acids, Metals & Fuels: Hydrochloric Acid And Indigestion Tablets Flashcards
Why does the stomach produce hydrochloric acid?
The stomach produces hydrochloric acid to help with digestion and to kill bacteria.
Describe how you could test effectiveness of indigestion tablets in a lab.
You could test how much acid a single tablet can neutralise. You can do this by dissolving a tablet in water in a conical flask and adding acid a bit at a time using a bursts. Use an indicator to tell when the solution has been neutralised. Record the volume of acid added to the conical flask. A more effective tablet will neutralise more acid.
What causes indigestion? How can it be treated?
Indigestion is caused by too much hydrochloric acid in the stomach. It can treated with indigestion tablets, which contain bases to neutralise the excess acid.
