It is based on vont hoff factor according to which more no. of ions in a sol. lead to more decrease in freezing point and more increase in boiling point. Here since BaSO4 is precipitited out no. of ions in sol. decreses due to which freezing point will increse and boiling point will decrease. Please do approve my answer if correct
