Question

why Baso4 is insoluable in water although it is an ionic compound?

Answer 1

BaS04 is insoluble in water although as it is an ionic compound because the size of Ba and so4 is very large as which leads to higher lactose enthalphy that of hydration enthalphy

Answer 2

compounds are generally soluble in polar solvents like water but insoluble in nonpolar organic solvent molecules of the floor polar solvent water can overcome the force of attraction between the ions in the Crystal of the ionic Solar Works as the result the ionic become mobile and whispers in the aldolase all directions in the polar solvents nonpolar organic solvents cannot overcome the forces of attraction between the ions of the ionic compounds are ionic compounds do not dissolve in nonpolar organic solvents
therefore Baso4 dissolve in water
