Flashcards for NSW HSC Chemistry, covering the Year 12 course from the Chemistry Stage 6 Syllabus: Module 5 Equilibrium and acid reactions, Module 6 Acid/base reactions, Module 7 Organic chemistry and Module 8 Applying chemical ideas, split by module and then by inquiry question in the syllabus's own order. Delete or suspend any subdeck your course leaves out once the deck is yours.

Adding it gives you your own copy, with every subdeck below. Each card then comes back just before you would forget it, and every one you get right or wrong counts towards your mastery of its topic. You can delete or suspend the parts you are not studying once it is yours.

Some of its cards

  • What is the purpose of an acid-base titration?
    To determine the unknown concentration of an acid or base, using a solution of known concentration
  • Why do alcohols have higher boiling points than alkanes of a similar chain length?
    The -OH group allows alcohol molecules to hydrogen bond with each other, which is a stronger intermolecular force than the dispersion forces alone that act between alkane molecules
  • Write the general equilibrium expression for Keq of the reaction aA+bB⇌cC+dD\mathrm{aA + bB \rightleftharpoons cC + dD}.
    Keq=[C]c[D]d[A]a[B]bK_{eq} = \dfrac{[C]^c[D]^d}{[A]^a[B]^b}
  • Why is monitoring the concentration of ions in the environment (for example in waterways) important?
    Adverse water quality can harm aquatic ecosystems and human health, so ion levels need to be tracked and controlled
  • Describe, in general terms, how an ionic solid dissolves in water.
    Polar water molecules surround and hydrate the cations and anions, overcoming the attraction between the ions in the lattice and dispersing them through the solution
  • What is a homologous series?
    A family of compounds with the same general formula and similar chemical properties, differing from one member to the next by a CH2\mathrm{CH_2} unit
  • What is a closed system, in the context of chemical equilibrium?
    A system that can exchange energy with its surroundings but not matter
  • What is the IUPAC name for hydrochloric acid?
    Hydrochloric acid
  • State Le Chatelier's principle.
    If a change is made to a system at equilibrium, the equilibrium position shifts to partially oppose that change
  • What functional group do aldehydes and ketones have in common?
    The carbonyl group, C=O
