🧪 The Purity Paradox
You pick up a bottle of "pure" orange juice. Sounds chemically pure, right? Wrong! In chemistry, that juice is a complex mixture of water, sugars, citric acid, vitamins, and flavour compounds. This is one of chemistry's most common exam tricks: the word "pure" means something very different in science compared to everyday life. A chemist's idea of pure means just ONE type of substance — nothing else mixed in. Nail this distinction and you are already ahead of half the class.
