2.3 Compounds, formulae and equations

Cards (11)

  • Transition metals can form ions with different charges which is determined by its oxidation number
  • Ionic compounds have a neutral charge overall
  • Balancing equations
    • write formulae of the reactants and products
    • multiply each formula until both sides contain the same number of each atom
  • Ionic equations don't use spectator ions
  • Nitrate ion = NO3-
  • Carbonate ion = CO3 2-
  • Sulfate ion = SO4 2-
  • Hydroxide ion = OH-
  • Ammonium ion = NH4-
  • Zinc ion = Zn 2+
  • Silver ion = Ag+
