A 0.1 molal aqueous solution of a weak electrolyte, HX, freezes at -0.208 °C. Assuming ideal behavior, what is the van't Hoff factor (i) for HX in this solution? (K$_f$ for water = 1.86 K kg mol$^{-1}$)

Which of the following solutions will have the highest boiling point ?

At $25^\circ C$ , the highest osmotic pressure is exhibited by 0.1 M solution of

The vapour pressure will be lowest of

Equimolar solutions of two non-electrolytes in the same solvent should have :

The molal elevation constant for water is ${\rm{0}}{\rm{.52}}\;{\rm{K}}\;{\rm{molalit}}{{\rm{y}}^{ - 1}}$. The elevation caused in the boiling point of water by dissolving 0.25 mole of a non-volatile solute in 250 g of water will be :

The spontaneous movement of solute particles from a more concentrated solution to less concentrated solution is called :

The phenomenon in which cells are shrinked down if placed in hypertonic solution is called :

Choose the correct statement.

When concentration of a salt solution is increased

At $27^\circ C$, the osmotic pressure of a solution containing 4.0 g solute (molar mass = 246) per litre at $27^\circ C$ is :$(R = 0.0821\;{\rm{atms}}.{\rm{mo}}{{\rm{l}}^{ - 1}}\;K)$
