What we did in 2 hours:

Congratulations, we have completed the syllabus! 🙂

Our last part of hypothesis testing looked at questions involving unknown parameters. It’s important to identify the approach to these, where the result of the test of given, and from there work in reverse to solve for the unknown. Hypothesis Testing is a very process specific chapter, so make sure you practice and internalise the process, and it’s easy marks!

What you take home:

Take-Away solutions for both of our Additional Lessons are linked here, together with the Chat Challenge solutions:

[J2 Chemistry PMCians] Reviewing Equilibrium!

What we did in 2 hours:

This week, we revised Acid-Base Equilibrium, In this revision lesson, we investigated the significance of acid/base equilibrium constants, and used them for pH calculations involving strong, weak reagents, salt and buffer solutions. Explanations of the mechanisms behind buffer solutions are discussed. All the knowledge culminated in the sketching of the titration curve.

What you take home:

Solutions to selected structured questions and homework are found here:
