Constructing ionic equations using the continuous variation methodThe ionic equation for the formation of an insoluble salt can be constructed if we know the number of moles of cation and anion reacted together to form 1 mole of the insoluble salt. For example: (a) 1 mole of silver chromate(VI) is formed from 2 moles of Ag+ ions and 1 mole of CrO42- ions. Ionic … [Read more...] about Constructing ionic equations using the continuous variation method
