Q

List (and explain where necessary) 4 properties of ionic compounds

A
  1. High MP/BP
  2. Do not conduct electricity unless dissolved or molten (ions can move and carry charge when molten otherwise they are in fixed positions).
  3. Brittle (if ions of the same charge meet, they will repel and structure will break).
  4. Soluble in polar solvents, eg. water
