Equilibrium - Result Question 77
####81. Equimolar solutions of the following substances were prepared separately. Which one of these will record the highest $pH$ value?
[2012]
(a) $BaCl_2$
(c) $LiCl$
(b) $AlCl_3$
(d) $BeCl_2$
Show Answer
Solution:
- (a) $.(AlCl_3, LiCl & BeCl_2))$ all these solutions are acidic due to cationic hydrolysis, whereas $BaCl_2$, is salt of strong base $(Ba(OH)_2)$ and strong acid $(HCl)$, hence it will have maximum $pH$.
