Barium sulphate is almost insoluble in water. It is not totally insoluble—very small amounts do dissolve. This is true of any"insoluble" ionic compound. If solid barium sulphate is shaken with water, a small amount of barium ions and sulphate ions break away from the surface of the solid and go into solution. read more
