6.  Salt Makers ( = Halogens), Halogenides and other Salts

salt01: Halogens = solid, liquid and gaseous "salt makers"
salt02: Sodium chloride synthesis from sodium and the "salt maker" chlorine..
salt03: Zinc salts of hydrochloric acid and other hydrogen halides
salt04: Heat of neutralisation: Synthesis of three sodium salts
salt05: Beilstein Test for halogen compounds

a Salts can increase or decrease plant growth
Minerals 1: Limestone
salt08: Limestone = A salt useful in nature, troublesome in households
salt09: Burning lime stone = endothermic decomposition
salt10: Slaking quicklime = exothermic reaction with water
