Sample cards from this deck

Definition
Acid-base titrations and curves: TCE Chemistry (Tasmania)
Define Equivalence point
The point in a titration at which the moles of added titrant exactly react with the moles of the analyte, in the ratio given by the balanced equation.
Definition
Analytical techniques: TCE Chemistry (Tasmania)
Define Molecular ion peak
The peak in a mass spectrum produced by the unfragmented ionised molecule. Its $m/z$ value gives the molar mass of the compound, the key starting point for working out a molecular formula.
Definition
Acids, bases and pH: TCE Chemistry (Tasmania)
Define Concentration
Concentration is how many moles of acid are dissolved per litre. A solution can be dilute but strong, or concentrated but weak. Keep the two ideas separate; this distinction is a perennial exam discriminator.
Definition
Bonding and intermolecular forces: TCE Chemistry (Tasmania)
Define Ionic bonding
Ionic bonding is the electrostatic attraction between oppositely charged ions in a three-dimensional lattice. It gives high melting points, hardness with brittleness (the lattice shatters when like charges are forced together), and electrical conductivity only when molten or dissolved.
Definition
Balancing redox half-equations: TCE Chemistry (Tasmania)
Define Half-equation
An equation showing either the oxidation or the reduction part of a redox reaction on its own, including the electrons lost or gained, balanced for both atoms and charge.
Definition
Chemical synthesis: TCE Chemistry (Tasmania)
Define Synthesis pathway
A planned sequence of chemical reactions that converts available starting materials, step by step, into a desired target molecule. Each step specifies the reagents and conditions needed for that particular transformation.
Definition
Buffer solutions: TCE Chemistry (Tasmania)
Define Buffer capacity
Buffer capacity is the amount of acid or base a buffer can absorb before the pH changes sharply. It is greatest when the two components are present in roughly equal, high concentrations. Once one partner is largely used up, the buffer fails and the pH swings rapidly.
Definition
Nomenclature and isomerism: TCE Chemistry (Tasmania)
Define Structural isomers
Compounds with the same molecular formula but different connectivity.
Definition
Catalysts and reaction rate: TCE Chemistry (Tasmania)
Define Heterogeneous catalysts
Heterogeneous catalysts are in a different state, commonly a solid with gaseous or liquid reactants. They adsorb reactant molecules onto active sites on their surface, weakening bonds and holding molecules in a favourable orientation; examples include iron in the Haber process and platinum or palladium in catalytic converters.
Definition
Organic families and reactions: TCE Chemistry (Tasmania)
Define Homologous series
A family of organic compounds with the same functional group and general formula, where consecutive members differ by a $CH_2$ unit. Members show similar chemical properties and a gradual trend in physical properties.
