Answer:
1-antacid neutralizes the acidity in your body from wich you get relief efforts
2-(again same) it neutralizes the ant bite acid
3-it can cause damage the living organisms which live in water
Answer:
Acidity is caused due to the excess production of acids in the stomach.
An antacid tablet contains bases, such as milk of magnesia(magnesium hydroxide, gelusil,etc.
These bases react with excess of acids and neutralize the effect of excessive acid and brings relief.
(b) Calamine solution is applied on the skin when an ant bites.
When an ant bites, it injects formic acid into the skin.
Calamine solution contains zinc carbonate which is basic in nature.
Hence, it is applied on the skin to neutralize the effect of formic acid.
(c) Factory waste is neutralised before disposing it into the water bodies.
Some factory waste contains acids.
If they are allowed to dispose of water bodies, it will harm aquatic lives.
Hence, these wastes are neutralized with basic chemicals before disposing into water bodies.
