Chapter 7 - Redox

Question 1

what is an oxidising agent

Answer 1

the oxidising agent takes the electrons of the substance that is oxidised and hence gets reduced

Question 2

what is a reducing agent

Answer 2

reducing agents get oxidised so they lose electrons
they donate electrons to the species they are reducing

Question 3

describe oxidation in terms of electrons

Answer 3

oxidation is loss
