Question

Which chemical is injected into the skin of a person during the nettle leaf hair sting?

How can the effect of this sting be neutralised?

Answer 1

Methanoic acid is injected into the skin during a nettle-leaf-hair sting. A nettle-leaf-hair sting is acidic, as methanoic acid is injected into the body, which causes severe pain and an itching sensation. Applying a baking soda solution (a base) on the skin soothes the pain by neutralising the acid. Thus, the effect of these stings is neutralised.
