    • A compound containing a group 7 element.
  4. Formulation (1) - C2:1
    • A mixture where components are carefully measured before being mixed to give a desired set of properties.
  5. Solution (1) - C2:1
    • A mixture where one of the substances is dissolved within another.
  6. Dilute (1) - C2:1
    • A solution containing a relatively small quantity of solute as compared with the amount of solvent.
  7. Pure (1) - C2:1
    • A substance made up of only one element and compound.
  8. Chromatography (1) - C2:1
    • A technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.
  9. Lime water (1) - C2:1
    • An aqueous solution of calcium hydroxide.
  10. Ion (1) - C2:1
    • An atom that has either gained or lost electrons.
  11. Rf Value (1) - C2:1
    • In chromatography is the distance travelled by a given component divided by the distance travelled by the solvent front.
  12. Stationary phase (1) - C2:1
    • The phase of a chromatography system on which the materials to be separated are selectively adsorbed.
  13. Boiling point (1) - C2:1
    • The temperature at which a given liquid will boil.
  14. Melting point (1) - C2:1
    • The temperature at which a given solid will melt.
  15. Instrumental method (1) - C2:1
    • The use of instruments to separate, identify, and quantify matter.
  16. Qualitative test (1) - C2:1
