🔩 Iron nail in copper sulfate: virtual chemistry experiment

A more reactive metal displaces copper: the nail turns pink and the blue fades to green.

▶ Launch this experiment free

Runs in your browser on any phone, tablet or laptop. No sign-up, no install, no chemicals needed.

What you'll do

  1. Add 2 g of iron (Solids → Iron nail)
  2. Watch copper coat the nail as the solution turns green
  3. Stir to speed it up

The chemistry behind it

Fe + CuSO₄ → FeSO₄ + Cu. Iron is above copper in the reactivity series, so it gives up electrons to Cu²⁺ ions.

Why do this experiment virtually?

Many school labs can't run this experiment safely or don't have the chemicals. In Faradium you set it up in seconds, repeat it as often as you like, change the amounts and see the real result: colours, gases, precipitates and temperature changes. The lab notebook records every observation with the balanced equation for your write-up.
