The Nature of Acids and Bases
Most people think of acids and bases as opposites, but what is opposite about them? The key to understanding acids and bases is water. Water ionizes to produce a small but equal amount of hydronium and hydroxide ions. Addition of acid causes the hydronium concentration to increase while hydroxide concentration decreases. Addition of base causes the hydroxide ion concentration to increase while the hydronium ion concentration decreases. The hydronium ion causes the acid's properties. The hydroxid

Redox: Determining What has been Oxidized and What has been Reduced
In order to properly interpret redox equations, it is necessary to know what has been oxidized, and what has been reduced. This PowerPoint presentation builds on other lessons to determine the oxidation states of every element involved on the reactant and product side of a redox equation. The equation is analyzed to see how the oxidation states have changed. The species with an increased oxidation state is identified as the substance oxidized, while the species with a decreased oxidation state i

Entropy and Gibbs Free Energy
Energy tends to dissipate through the universe. As a result the overall entropy of the universe is always increasing. For secondary students, entropy is best understood by its relationship to randomness or disorder. This PowerPoint presentation provides a basis for students to understand when the entropy increases or when it decreases during chemical or physical changes. It also explores the natural tendency for entropy to increase, and provides examples that illustrate why it takes work to decr

Stoichiometry: Percent Yield
This NGSS aligned lesson builds on the stoichiometry and limiting and excess reactants concepts. The emphasis of this lesson is on concept development of percent yield. Students will distinguish between actual yield, theoretical yield, and percentage yield. Conceptually, students will understand that the percent yield tells chemists about the efficiency of a reaction. Chemists can then work to improve efficiency in several different ways, and increase percent yield. Students will calculate pe

S3.1 Discontinuities in Ionisation Energy, HL (IBDP Chemistry)
This PowerPoint lesson explains discontinuities in first ionisation energy for IBDP Chemistry HL (first examination 2025), helping students understand deviations from periodic trends. It provides a clear, structured explanation of how these discontinuities give evidence for sublevels and electron pairing. Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms to form one mole of gaseous 1+ ions. Across a period, first ionisation energy generally i
