AP® Chemistry Beta
Tools
Chemistry trainers and drills: justifications, particle diagrams, equilibrium and buffer drills, titration curves, each followed by questions.
Trainers
Work through a model or a representation, then answer questions about it.
- Particle diagramsWater around ions, limiting reactants, equilibrium counts and acid strength, drawn particle by particle.Representations of SolutionsOpen
- Q vs KQ from numbers or particles, the direction of the shift, and the wording that earns the point.Reaction Quotient and Le Châtelier's PrincipleOpen
- Titration curve readerEquivalence, half-equivalence and pKa, indicator choice and the species at each point.Acid-Base TitrationsOpen
Skills tools
The math and data skills the exam tests, with worked steps.
Drills
Seeded, unlimited calculation drills, checked step by step.
- ICE table drillsBuild the I, C and E rows step by step; every slip gets its own feedback.Calculating Equilibrium ConcentrationsOpen
- Buffer and Henderson-Hasselbalch drillsBuffer pH, target ratios, added acid or base and capacity, checked step by step.Henderson-Hasselbalch EquationOpen
Every tool records what you answer: missed questions go into your review queue, and your accuracy shows here and on the dashboard.
