At $25 \, ^\circ C$,the $pH$ value of a solution is $6$. The solution is:

What is the normal $pH$ range of human blood?

At $90\,^oC$,pure water has $[H^{+}] = 10^{-6}\,M$. If $100\, mL$ of $0.2\, M\, HCl$ is added to $200\, mL$ of $0.1\, M\, KOH$ at $90\,^oC$,then the $pH$ of the resulting solution will be:

Identify the incorrect statement.

An aqueous solution tends to have a $p^H$ of $0$. Then the solution will be .....

The $pH$ of water at $25\,^oC$ is nearly
