More science!

We had a visit from Jeremy Buckley (Quincey Buckley's Dad) today.  He is very enthusiastic about science and has loads of knowledge.  He shared a few science REDOX experiments with us...

Redox (shorthand for reduction/oxidation) describes all chemical reactions in which atoms have their oxidation number(oxidation state) changed.
The term redox comes from the two concepts of reduction and oxidation. It can be explained in simple terms:
  • Oxidation describes the loss of electrons by a molecule, atom or ion
  • Reduction describes the gain of electrons by a molecule, atom or ion
Which gains and loses electrons can be easily memorised by the abbreviation OIL RIG, which stands for, "Oxidation Is Loss," or losing electrons, and "Reduction Is Gain," or gaining electrons.

But there are exceptions.
