ASFC Chemistry

AS: Equilibrium features and concentration changes

An overview of the features of a dynamic equilibrium and how changes in concentration can effect the position of the equilibrium.

AS: Heating to constant mass

This includes practical points about why you may get more or less molecules of H2O found in the calculation! A must for any student who has forgotten this procedure.

AS: Calculations of Q

Looking at the terms of Q=mc'delta'T

AS: Complete ionisation summary

A complete summary of the different trends and facts you need to know for ionisation energy on the OCR A specification. All in just over 5 minutes! Such value!

AS: Bonding overview

Here I talk about the 4 different types of lattice structure and mention briefly about how to spot the difference in boiling points between giant ionic and simple molecular. I also got some reason say 'keep you listening' right at the end. No idea.

AS: Titration procedures

If you had to describe the method of a titration, what would you say? What are concordat results. I take you through what we expect OCR are looking for based on our experience.

AS: Electrons

In this podcast I take you through the essentials of how electrons are distributed between the shells, sub shells and orbitals of an atom. I'll use sodium as my example throughout but for more examples you can check out our YouTube channel.
