The colligative property of a solution depends on.....

What happens to the boiling point and freezing point of water when sugar is added to it?

Which observation$(s)$ reflect$(s)$ colligative properties?
$(i)$ $A$ $0.5 \ m$ $NaBr$ solution has a higher vapour pressure than a $0.5 \ m$ $BaCl_2$ solution at the same temperature
$(ii)$ Pure water freezes at the higher temperature than pure methanol
$(iii)$ $A$ $0.1 \ m$ $NaOH$ solution freezes at a lower temperature than pure water
Choose the correct answer from the codes given below

Which one of the following aqueous solutions will exhibit the highest boiling point?

Equimolal solutions of non-electrolytes in the same solvent have:

Assertion : The water pouch of an instant cold pack for treating athletic injuries breaks when squeezed and $NH_4NO_3$ dissolves,lowering the temperature.
Reason : Addition of a non-volatile solute into a solvent results in the depression of the freezing point of the solvent.
