Which observation(s) reflect(s) colligative
properties?
(i) A $0.5 \mathrm{~m}$ NaBr solution has a higher vapour pressure than a $0.5 \mathrm{~m} \mathrm{BaCl}_{2}$ solution at the same temperature
(ii) Pure water freezes at the higher temperature than pure methanol
(iii) A $0.1 \mathrm{~m} \mathrm{NaOH}$ solution freezes at a lower temperature than pure water Choose the correct answer from the codes given below
  1. (i), (ii) and (iii)
  2. (i) and (ii)
  3. (ii) and (iii)
  4. (i) and (iii)

Solution

Colligative properties depends upon the no. of particles. Since methanol is non electrolyte hence cannot be considered.
