Among the following 0.10 m aqueous solutions, which one will exhibit the largest freezing point depression?A. KClB. `C_(6)H_(12)O_(6)`C. `Al_(2)(SO_(4))_(3)`D. `K_(2)SO_(4)` |

Answer» Correct Answer - c As we know, `DeltaT_(f) = ixxK_(f)xxm` where, `K_(f)` and m are constants. `(a) KCl(aq) overset(DeltaT_(f)propi)(hArr)K^(+)(aq)+Cl^(-)(aq),(i=2)` `(b) C_(6)H_(12)O_(6) hArr No ions` `(c) Al_(2)(SO_(4))_(3)(aq) harr 2 Al^(3+) + 3SO_(4)^(2-), (i=5)` `(d) K_(2)SO_(4)(aq) hArr 2k^(+) + SO_(4)^(2-), (i = 3)` Hence, `Al_(2)(SO_(4))_(3)` will exhibit largest freezing point depression due to the highest value of i. |
