Question Stem
The boiling point of water in a 0.1 molal silver nitrate solution (solution A) is x $$^\circ$$C. To this solution A, an equal volume of 0.1 molal aqueous barium chloride solution is added to make a new solution B. The difference in the boiling points of water in the two solutions A and B is y $$\times$$ 10$$^{-2}$$ $$^\circ$$C.
(Assume: Densities of the solutions A and B are the same as that of water and the soluble salts dissociate completely.
Use: Molal elevation constant (Ebullioscopic Constant), $$K_b$$ = 0.5 K kg mol$$^{-1}$$; Boiling point of pure water as 100 $$^\circ$$C.)
