Barium chloride on reacting with sodium sulphate forms barium sulphate and sodium chloride. Which of the following is the precipitate?
The reaction involved: Barium chloride(solution)+Sodium sulphate(solution)→Barium sulphate(white ppt.)↓+ Sodium chloride(solution) ,
when barium chloride reacts with sodium sulphate, it forms white precipitate of barium sulphate along with sodium chloride. Because a precipitate is an insoluble solid. And here, sodium chloride, barium chloride and sodium sulphate is in the solution form.
