Answer 1

Answer:

i) An antacid contains bases which neutralize the HCl (Hydrochloric acid) in the stomach and relieves the pain of acidity

ii) A bite of an ant contains Formic acid. To neutralize this acid, we use a calamine solution containing zinc carbonate

iii) The wastes disposed by factories contains a lot of acids dissolved in it. This is dangerous for the water and the aquatic life in it. So, it is neutralized before disposing it into water bodies

Answer 2

Explanation

1. Because an antacid tablet is basic in nature and it makes the acid forming inside our body Neutral.
2. Sting of ant contains formic acid so it irritates the skin but calamine solution is basic as it contains zinc carbonate oxide and it stops irritation.
3. That is because Factory Waste contains a huge amount of acid which may harm aquatic life , thats why the are neutralized before disposing in water bodies.
