What this test covers

4 key concepts, tested the way the exam tests them.

Mapped from EduPeak’s learning framework for this chapter — the same map your report scores you against.

  1. 1
    Chemical equilibrium and K
    • Applies the law of mass action, relates Kp and Kc, and computes equilibrium compositions.Apply & Analyse
  2. 2
    Le Chatelier’s principle
    • Predicts equilibrium shifts under concentration, pressure, temperature and catalyst changes.Apply & Analyse
  3. 3
    Ionic equilibrium: acids, bases and pH
    • Computes pH for strong/weak acids and bases and applies ionisation constants.Apply & Analyse
  4. 4
    Buffers, hydrolysis and solubility equilibria
    • Applies Henderson-Hasselbalch, salt hydrolysis and Ksp with the common-ion effect.Apply & Analyse

SampleChemistry· Numerical+4 / 0
The titration curve of a weak acid against a strong base using phenolphthalein as indicator is shown below, with (given ).
The number of the following statements which is/are correct about phenolphthalein is:
(A) It can be used as an indicator for the titration of a weak acid with a weak base.
(B) It begins to change colour at .
(C) It is a weak organic base.
(D) It is colourless in acidic medium.
Titration curve for a weak acid against a strong base. The vertical axis is pH, marked at 6, 8, 10 and 12; the horizontal axis is the volume of NaOH added, marked 0, 5, 10, 15, 20 and 25. The curve rises gradually to about pH 6, then jumps almost vertically near 10 mL of NaOH up to about pH 10, after which it climbs slowly toward pH 13. A dotted line marks the steep equivalence region at about 10 mL.
