🇬🇧 Chlorine meaning: English Vocabulary Flash Card

Chlorine is a chemical that is a greenish-yellow gas with a very strong, sharp smell. People add chlorine to swimming pools and drinking water to kill tiny germs that can make us sick. Chlorine is powerful, so it must be used in the right amount, and you should never breathe in a lot of it or touch the pure gas. In small, carefully controlled amounts, chlorine helps keep our water clean and safe to use.
