Which one of the following in the ratio of the lowering of V.P. of 0.1 M aqueous solution of `BaCl_(2)`,NaCl and `Al_(2)(SO_(4)_(4)` respectively?A. `2 : 3 : 5 `B. `3 : 2 : 5 `C. `5 : 2 : 3 `D. `5 : 1 : 2 ` |

Answer» Correct Answer - B `BaCl_(2) rarr Ba^(2+) + 2CI^(-)(3 "ions")` `NaCl rarr Na^(+) + CI^(-) (2 "ions")` `Al_(2)(SO_(4))_(3) rarr 2Al^(3+) + 3SO_(4)^(2-) (5"ions")` lowering of V.P. ratio = 3 : 2 : 5 respectively as lowering of V.P. |
