Chemical And Ionic Equilibrium Result 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 $7$
Show Answer
Answer:
Correct Answer: 35. ( d )
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 $7$.
