•Testing for sulfate ions
Sulfate ions in solution, SO4 2 -, are detected using barium chloride solution. The test solution is acidified using a few drops of dilute hydrochloric acid, and then a few drops of barium chloride solution are added. A white precipitate of barium sulfate forms if sulfate ions are present
• solubility of the product of nickel(ii) ion and hydroxide ion is insoluble.
