A) \[SrC{{l}_{2}}\]
B) \[BaC{{l}_{2}}\]
C) \[MgC{{l}_{2}}\]
D) \[CaC{{l}_{2}}\]
Correct Answer: B
Solution :
Key Idea: As the basic nature increases, pH increases pH of base > 7 pH of acid < 7 In alkaline earth metals on moving downward the size of cation increases, thus basicity increases. Hence, the increasing order of basicity is as: \[MgC{{l}_{2}}<CaC{{l}_{2}}<SnC{{l}_{2}}<BaC{{l}_{2}}\] Therefore, the solution of \[BaC{{l}_{2}}\] will record the highest pH.You need to login to perform this action.
