Equilibrium
Equimolar solutions of the following were prepared in water separately which one of the solutions will record the highest pH?
SrCl2
BaCl2
MgCl2
CaCl2
B.
BaCl2
As the basic nature 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 or basicity is as:
MgCl2 < CaCl2 < SnCl2< BaCl2
Therefore, the solution of BaCl2 will record the highest pH.
