प्रश्न
Explain two neutralisation reactions related to daily life situations.
उत्तर
(a) Indigestion: Due to indigestion a large amount of acid is released into the stomach which causes acidity. This acid is neutralised by taking antacids like milk of magnesia.
(b) Ant’s sting: Ant’s sting releases formic acid in the skin. It can be neutralised by rubbing baking soda or putting in calamine lotion.
