Flashcards for the Leaving Certificate Chemistry specification introduced in schools from September 2025, split into its five strands and then by topic in the specification's own order. Higher-level-only cards say so. 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 colour is Fehling's solution before it is used in a test?
    Blue
  • What is a hydrocarbon?
    An organic compound made up of carbon and hydrogen atoms only
  • What is a surfactant?
    A molecule with a water-attracting (hydrophilic) part and a water-repelling (hydrophobic) part
  • What does it mean to evaluate a media-based argument about a scientific issue?
    To judge how well the evidence given actually supports the claim being made, rather than accepting the claim on its own
  • Give one everyday substance that is acidic.
    Vinegar
  • What is a galvanic (voltaic) cell?
    A cell in which a spontaneous redox reaction produces a flow of electrons, converting chemical energy into electrical energy
  • Using the main energy level (shell) arrangement, what is the maximum number of electrons in the first energy level?
    2
  • What is meant by describing chemical bonding as a continuum from ionic through to pure covalent?
    There is no sharp division between bond types; a bond can range from a full transfer of electrons (ionic) through unequal sharing (polar covalent) to equal sharing (pure covalent)
  • What is the difference between an intramolecular force and an intermolecular force?
    An intramolecular force holds the atoms of a molecule together; an intermolecular force acts between separate molecules
  • What is the first ionisation energy of an element?
    The energy required to remove one electron from each atom in one mole of its gaseous atoms in their ground state
