Topic 12 – Acid-base equilibria
This topic builds a quantitative framework into our understanding of acids, enabling us to calculate the pH of strong acids, weak acids and [...]
Topic 13 – Energetics II
The Year 13 Energetics topics introduces some very important concepts that underpin much of our understanding of chemistry. The first (and l [...]
Topic 11 – Equilibrium II
This topic builds on the basics of equilibria covered during the Year 12 content to bring in the maths, with calculations of equilibrium con [...]
Topic 1: Stoichiometric Relationships (2016)
Stoichiometry deals with all the stuff about the amounts of chemicals involved and produced in chemical reactions, and the ratios in which t [...]
Uncertainty Calculations
In mathematics, when you do a sum, the answer is the answer and that is the end of the story. In science however this is different because t [...]
Topic 6: Kinetics
Kinetics is all about the rate at which chemical reactions happen and the factors that govern this. At SL, this means consolidating the unde [...]
Calculations for IB Chemistry
To do well in IB Chemistry you need to master about 50 different types of calculation, so I have gathered them all together here in one plac [...]
Energetics: Student-made resources
Please find below the resources produced by the groups for the student-taught lessons on the use of enthalpies of formation and combustion. [...]
Topic 5: Energetics
Energetics (aka thermodynamics) is the study of energy in chemical reactions, and is central to giving us a deeper understanding of the way [...]
Bond Enthalpy Experiment Calculations
The calculations below show you how to determine the expected temperature rise. Step 1: calculate molar concentration of H2O2 Step 2: [...]
Internal Assessment
Overview The internal assessment for chemistry requires you to produce a portfolio of investigations, each of which are marked according to [...]
Topic 8: Acids and Bases
Acids and bases are some of the most familiar compounds in everyday life, and most people have at least a rudimentary understanding o [...]
Topic 9: Oxidation and Reduction
Oxidation and reduction (aka redox) reactions are those where atoms change their oxidation state, meaning they have either gained or [...]
Topic 1: Quantitative Chemistry (2009)
Stoichiometry deals with all the stuff about the amounts of chemicals involved and produced in chemical reactions, and the ratios in which t [...]
