If the freezing point of a 0.01 molal aqueous solution of a cobalt(III) chloride-ammonia complex (which behaves as a strong electrolytes) is `-0.0558^(@)C`, the number of chloride(s) in the coordination sphere of the complex is [`K_(f)` of water `=1.86 Kkgmol^(-1)`] |
Answer» Correct Answer - 1 `Delta T_(f)=K_(f)xx ixx m rArr 0.0558=1.86xx ixx0.01` i=3 Given complex behaves as a strong electrolyte `alpha = 100%` n = 3(no. of particles given by complex) `therefore` complex is `[Co(NH_(3))_(5)Cl]Cl_(2)` no. of `Cl^(-)` ions in the co-ordination sphere of the complex = 1 `Delta T_(f)=K_(f)xx ixx m` `0.0558=1.86xx ixx0.01` i = 3 |
