Question

The poisonous effect of acid present in stings of bees and ants can be neutralised by the use of solution that contains
a) Acetic acid
b) Formic acid
c) Sodium hydroxide
d) Sodium chloride​

Answer 1

The poisonous effect of acid present in stings of bees and ants can be neutralised by the use of a solution that contains b) Formic acid

• Formic acid (Methanoic acid) is present in bee venom. But it is not the sole chemical that causes pain, it also contains histamine which is a kind of allergen and hyaluronidase.
• The acid from a bee sting produces pain and irritation. Applying a moderate base, such as baking soda, to the stinging region will assist provide relief.

Answer 2

The correct option is C.

• The string of bees and ants have formic acid.
• This acid has a poisonous effect.
• We know that any acid can be neutralised by the base.
• So, the formic acid present in bee and ant string can be neutralised by any base like sodium hydroxide.
• Sodium chloride is salt so, it can not neutralise the acid.
