Equilibrium - Result Question 84
####88. Equimolar solutions of the following were prepared in water separately. Which one of the solutions will record the highest $pH$ ?
[2008]
(a) $SrCl_2$
(b) $BaCl_2$
(c) $MgCl_2$
(d) $CaCl_2$
Show Answer
Solution:
- (b) The highest $pH$ will be recorded by the most basic solution. The basic nature of hydroxides of alkaline earth metals increase as we move from $Mg$ to $Ba$ and thus the solution of $BaCl_2$ in water will be most basic and so it will have highest $pH$.
