MCQ
The freezing point of equimolal aqueous solution will be highest for
  • A
    ${C_6}{H_5}NH_3^ + C{l^ - }$ (aniline hydrochloride)
  • B
    $Ca{(N{O_3})_2}$
  • C
    $La{(N{O_3})_3}$
  • ✓
    ${C_6}{H_{12}}{O_6}$ (glucose)
✓

Answer

Correct option: D.
${C_6}{H_{12}}{O_6}$ (glucose)
d
(d) $La{(N{O_3})_3}$ will furnish four ions and thus will develop more lowering in freezing point whereas glucose gives only one particle and thus minimum lowering in freezing point.
