A) KCl
B) \[KN{{O}_{3}}\]
C) \[{{K}_{2}}S{{O}_{4}}\]
D) \[{{K}_{3}}[Fe{{(CN)}_{6}}]\]
Correct Answer: D
Solution :
[d] \[Fe{{\left( OH \right)}_{3}}\] is positive sol. \[{{K}_{3}}[Fe{{(CN)}_{6}}]\]will provide \[{{[Fe{{(CN)}_{6}}]}^{3-}}\] for coagulation having highest magnitude of \[-ve\] charge among given options.You need to login to perform this action.
