Consider the following statements
(a)
The pH of a mixture containing $\displaystyle 400$ mL of $\displaystyle 0.1 \mathrm{M} \mathrm{H}_2 \mathrm{SO}_4$ and $\displaystyle 400$ mL of $\displaystyle 0.1$ M NaOH will be approximately 1.3.
(b)
Ionic product of water is temperature dependent.
(c)
A monobasic acid with $\displaystyle \mathrm{K}_{\mathrm{a}}=10^{-5}$ has a $\displaystyle \mathrm{pH}=5$. The degree of dissociation of this acid is $\displaystyle 50$%.
(d)
The Le Chatelier's principle is not applicable to common-ion effect.
The correct statements are :
