  Used to test for sulfate ions, forms white precipitate.
• Elements more/less soluble down the group as metal hydroxide

  more
• Elements more/less soluble down the group as metal sulfate

  less
• precipitate produced and there is an ionic equation if...(soluble/insoluble)

  insoluble
• Ionisation energy increases/decreases down a group.

  decreases
• Reactivity with water increases/decreases down the group

  increases as electrons easier to lose
