Question 1

What is the definition of a redox reaction?

Answer 1

A redox reaction is the simultaneous oxidation and reduction processes.

Question 2

If a half equation has electrons on the left side is it oxidation or reduction?

Answer 2

If a half equation has electrons on the left side it is reduction

Question 3

If a half equation has electrons on the right side is it oxidation or reduction?

Answer 3

If a half equation has electrons on the right it is oxidation

Question 4

What are the 5 steps to writing half equations in acidic conditions?

Answer 4

KOHES
Balance the Key elements
Balance the Oxygen by adding H20
Balance the Hydrogens by adding H+
Balance the charges by adding electrons
Add states to the half-equation

Question 5

What are the 7 steps to writing half equations in acidic conditions?

Answer 5

KOH(OH-)(H20)ES
Balance the Key elements
Balance the Oxygen by adding H20
Balance the Hydrogens by adding H+
Neutralise H+ by adding OH- to each side of the equation
Combine OH- and H+ to make water and cancel out where possible
Balance the charges by adding electrons
Add states to the half-equation
