Question
Explain two neutralisation reactions related to daily life situations.
✓
Answer
- Ant bite: When an ant bite injects the acidic liquid (formic acid) into the skin, the effect of the acid can be neutralised by rubbing moist baking soda (sodium hydrogen carbonate) or caiamine solution, which contains zinc carbonate.
- Indigestion: Our stomach contains hydrochloric acid. It helps $US$ to digest food but too much of acid in the stomach causes indigestion. Sometimes, indigestion is painful. To relieve indigestion, we take an antacid such as milk of magnesia which contains magnesium hydroxide. It neutralises the effect of excessive acid.
