A) \[{{K}_{2}}S{{O}_{4}}\]
B) \[{{K}_{3}}[Fe{{(CN)}_{6}}]\]
C) \[Al{{(N{{O}_{3}})}_{3}}\]
D) \[{{K}_{4}}[Fe{{(CN)}_{6}}]\]
Correct Answer: D
Solution :
\[A{{l}_{2}}{{(S{{O}_{4}})}_{3}}2A{{l}^{3+}}+3SO_{4}^{2-}\] Value of Van?t Hoff?s factor \[(i)=5\] (a) \[{{K}_{2}}S{{O}_{4}}2{{K}^{+}}+SO_{4}^{2-}\] \[(i=3)\] (b)\[{{K}_{3}}[Fe{{(CN)}_{6}}]3{{K}^{+}}+{{[Fe{{(CN)}_{6}}]}^{3-}}\] \[(i=4)\] (c)\[Al{{(N{{O}_{3}})}_{3}}A{{l}^{3+}}+3NO_{3}^{-}\] \[(i=4)\] (d) \[{{K}_{4}}[Fe{{(CN)}_{6}}]4{{K}^{+}}+{{[Fe{{(CN)}_{6}}]}^{3-}}\] \[(i=5)\] Therefore, \[{{K}_{4}}[Fe{{(CN)}_{6}}]\] has same value of i that of \[A{{l}_{2}}{{(S{{O}_{4}})}_{3}}\]i.e. \[i=5\]You need to login to perform this action.
