Stoichiometry

  1. What is a standard solution?
    A solution of accurately known concentration
  2. What can a standard solution be prepared from?
    A primary standard
  3. What characteristics must a primary standard have?
    • High state of purity
    • Stability
    • Solubility
    • Reasonably high formula mass
  4. What is the equivalence point of a reaction?
    The point at which the reaction is just complete
  5. What is the 'end point' of a reaction?
    The point at which a change is observed and associated with the equivalence point
  6. What is an indicator?
    A substance which changes colour at the end point
  7. What is EDTA and what is it used for?
    EDTA is an important complexometric reagent and can be used to determine the concentration of metal ions such as nickel (II)
  8. Why is potassium manganate a useful reactant in redox titrations?
    As it can act as its own indicator
