Q

what is a reducing agent

A

donates electrons to the species being reduced
therefore, loses electrons and is oxidised (increase in oxidation number for the reducing agent)

Q

what do oxidation & reduction result in?

A

oxidation= oxidation number becomes more positive
reduction= oxidation number becomes more negative

Q

what is an oxidising agent?

A

accepts electrons from the species being oxidised
- therefore, gains electrons + is reduced (reduction in oxidiation number)

Q

what happens in a disproportionation reaction?

A

a species is both oxidised and reduced, seen as both an increase and decrease in oxidation number for that species
eg. Cl2 + H2O —> ClO- + Cl- + 2H+
