Question

a) name the acid produced in our stomach. What happens when there is an excess secretion of acid in the stomach? How can its effect be cured? (b) explain how ph change is the cause of tooth decay? How it can be prevented?

Answer 1

A.Hydrochloric acid is produced in our stomach. The excess acid in the stomach causes indigestion whichproduces pain and irritation. Thiseffect can be cured by using antacids. Antacids (a group of mild bases) react with excess acid in the stomach and neutralise it

B.the lower pH of the mouth creates an optimal environment for bad bacteria, which eventually causes tooth decay. the pH of your mouth can changedepending on what foods you are eating.the basic compound of toothenamel calcium phosphate is attacked by acids thus to prevent BN it you need to neutralize the effect

Answer 2

HCl(hydro caloric acid) is produced. When there is excess one may face situation like acidity. It can be cured by taking antacids.

When ph of the tooth increased it causes corrosion of the enamel of the tooth which in turn becomes a cavity
