Redox And Electrode Potentials

Question 1

What is an oxidising agent?

Answer 1

Oxidises something else, reduces itself

Question 2

What is a reducing agent

Answer 2

Reduces something else, oxidises itself

Question 3

Why must a reaction have an overall positive electrode potential value?

Answer 3

So it is feasible, if the value is negative the reaction is not possible

Question 4

When given two equations and E/V values, which is oxidation and which is reduction

Answer 4

The one which is most positive is reduction,

The other must be switched around and this is oxidation
