Evaluate the following statements for their correctness. A. The elevation in boiling point temperature of water will be same for 0 . 1 M NaCl and 0 . 1 M urea. B. Azeotropic mixture boil without change in their composition. C. Osmosis always takes place from hypertonic to hypotonic solution. D. The density of 32 % H 2 SO 4 solution having molarity 4 . 09 M is approximately 1 . 26 g mL – 1 . E. A negatively charged so

Step-by-step solution

(A) Elevation in boiling point ( ∆ T b ) temperature of the water is not same, as ‘ i ’ value is different for two solutions. (B) Azeotropic mixture: Liquid mixtures that distill over without changes in composition are called constant boiling mixtures or Azeotropes or Azeotropic mixtures. (C) Osmosis always takes place from hypotonic (low concentration of solute) solution to hypertonic (high concentration of solute) solution. (D) Let the mass of H 2 SO 4 ( 32 % ) is 100. ∴ Weight of H 2 SO 4 = 32 Moles of H 2 SO 4
