Crystal for a Christmas Tree – Science at work

#Christmas #Science #Chemistry

 

In the clip, a copper tree turns into a silver covered tree, which looks like a snow covered tree.

 

For those thinking of replicating the experiment, be prepared to fork out about $ 100.

 

You can do a much cheaper experiment (less than $ 1). Dip an iron nail into a copper sulphate solution. The iron nail will turn into a copper nail, almost immediately!

 

The copper-iron and copper-silver interaction are examples of reduction and oxidation reactions. Oxidation and reduction reactions make mirrors possible where silver is deposited on glass and copper is deposited on the silver layer.

 

Thanks for the link Alexander and Anderson.
