  • Question 1
    4 / -1

    What will be the ratio of elevation in boiling point of aqueous solution of 1 m sugar, 1 CsCl, and 1 m Na2SO4 ? (Assume that ionic solid substances completely dissociates in the solution)

  • Question 2
    4 / -1

    At constant temperature, solubility of which of the following substances decreases with increase in temperature ?

  • Question 3
    4 / -1

    At constant temperature, in a closed vessel, an ideal solution is formed by liquid – A and liquid – B; and mole-fraction of A and B are 0.6 and 0.4 respectively. If vapour pressure of pure liquids are 125.0 and 62.5 mm respectively, then their mole-fraction in vapour state are respectively – (In vessel, no other component is in gaseous form)
