Imagine heating blue copper sulfate crystals in a test tube — they turn white as water escapes. Now add a few drops of water back… and they turn blue again. The same reaction, running in reverse. This isn't a trick: the product of the forward reaction becomes the reactant of the backward reaction. This is reversible chemistry, and it changes everything about how we think about reactions — because in a closed system, the reverse reaction starts immediately after the forward one.
🚪 The Revolving Door Analogy
Reversible reactions are like a revolving door! People can go in (forward reaction) AND come out (backward reaction) through the same door. Both directions happen at the same time. The ⇌ symbol shows this two-way traffic. Just like a revolving door, both processes are happening constantly — it just looks still when the same number enter as leave!
