Chemical and Ionic Equilibrium 2 Question 35
35. The $\mathrm{pH}$ of $10^{-8} \mathrm{M}$ solution of $\mathrm{HCl}$ in water is
$(1981,1 \mathrm{M})$
(a) 8
(b) -8
(c) between 7 and 8
(d) between 6 and 7
Objective Questions II
(One or more than one correct option)
Show Answer
Solution:
- No matter, what is the concentration of $\mathrm{HCl}$, its $\mathrm{pH}$ will always be less than 7 at $25^{\circ} \mathrm{C}$. In the present case, the solution is very dilute, $\mathrm{pH}$ will be between 6 and 7 .
