A Level H2 Chemistry: Stoichiometry, Mole Concept and Redox

Stoichiometry, mole concept and redox are the first few topics you will learn in your A Level Chemistry. In this course, I've divided it into two parts. Part (1) is on mole concept and stoichiometry, while part in part (2) we will look at redox. 

We will start off with mole concept and stoichiometry by revising the following topics learned in O Leve:

• Finding relative atomic mass (Ar) and relative molecular mass (Mr)

• What's mole and Avogadro's constant

• What's molar mass and finding molar mass

• Finding moles from mass

• Finding mole ratio from chemical equations or stoichiometry

• Percentage composition

• Finding empirical and molecular formulae

• Finding volume of gases

• Concentration (in mol/dm3 and g/dm3)

• Limiting and excess reagents in chemical calculations

• Finding percentage purity and percentage yield

Then we will go on to cover the following topics:

• Dilution

• Titration

• Back titration

• Go through A Level Chemistry questions on mole concept and stoichiometry

Next, we will cover redox. In redox, we start off by revising the topics covered in O Level:

• Oxidation and reduction ( in terms of oxygen, oxidation number, electrons and hydrogen)

• oxidising and reducing agents

Next, we will cover new concepts:

• Writing redox half equations in acidic and alkaline medium

• Common redox reactions

• Go through A Level questions on redox

To be able to do well in this course, you will need to have good basic foundations in chemistry which include writing formula of compounds/ molecules, and writing chemical and ionic equations.

This course covers the first few topics you will learn in A Level Chemistry, and are important topics to help you build your foundation in Chemistry. So try this course, and build up a good foundation in A Level Chemistry, so that you'll ace this subject.
