This blog will cover and explain the specification for Edexcel triple science course 2013 Chemistry. Hope it helps :)
reduction (as in loosing)
this is incorrect, Using OILRIG as in oxidation is loss and reduction is gain
# Oxidation is the loss of electrons or an increase in oxidation state by a molecule, atom, or ion.# Reduction is the gain of electrons or a decrease in oxidation state by a molecule, atom, or ion
...of elections.For this spec. point they're asking about in terms of oxygen and Hannah's description is correct for that.
She is right in the terms of oxygen. Oxidation is gain of oxygen. Reduction is loss of oxygen.OIL RIG mean Oxidation IS LOSS OF ELECTRONS. Reduction IS GAIN OF ELECTIONS.
