Precipitation reactions are those reaction in which a highly insoluble salt is formed as the product. The solubility of a precipitate depends upon its solubility product. Precipitate may be colorless or have range of colors.Barium ions can be separated out only when they get precipitated with any of the ion with which calcium ions do not get precipitated. Barium ions combine with chromate ions to forms precipitate called as barium chromate but calcium also form precipitate with chromate. So, this ion cannot be used to separate barium ions from the calcium ions. Barium ions combine with iodate ions to forms precipitate called as barium iodate but calcium also form precipitate with iodate. So, this ion cannot be used to separate barium ions from the calcium ions. Barium ions combine with carbonate ions to forms precipitate called as barium carbonate but calcium also form precipitate with carbonate. So, this ion cannot be used to separate barium ions from the calcium ions. Barium ions combine with dichromate ions to forms precipitate called as barium dichromate and calcium does not form precipitate with dichromate. So, this ion can be used to separate barium ions from the calcium ions. Barium ions combine with fluoride ions to forms precipitate called as barium fluoride but calcium also form precipitate with fluoride. So, this ion cannot be used to separate barium ions from the calcium ions. So, the only anion which can be used to separate barium ions from the calcium ions is dichromate that is Cr2O72-.
