Q. Statement 1 : pH of acidic solution is always below $7$ at $25^{\circ} C$
Statement 2 : At $25^{\circ} C$, the pH of $10^{-8} M HCl$ is $8$

Equilibrium

Solution:

(A) is correct
Since $K_w$ at $25^{\circ} C =10^{-14}$
So $pH$ of acidic solution $<7$ at $25^{\circ} C$
(R) is wrong. $pH$ of $10^{-8} M\, HCl =6.98$
