WitrynaThis should result in the formation of a white precipitate. The chemical equation of the reaction is : N a 2 S O 4 + B a C l 2 → B a S O 4 + 2 N a C l. 2) Add a little hydrochloric acid to the white precipitate formed. If the white precipitate formed is insoluble in the acid then the given salt is a sulphate. Witryna15 sie 2024 · Characteristic Reactions of Strontium Ions (Sr²⁺) James P. Birk.
