The $pH$ of a solution having $[H^{+}] = 10 \times 10^{-4} \, \text{moles/litre}$ will be

If the $pH$ of a solution increases from $3$ to $6$,then its $H^{+}$ ion concentration:

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

At a certain temperature $T$,if the conductivity of pure water is $5.5 \times 10^{-7} \ S \ cm^{-1}$,calculate the $pH$ of water at the given temperature. Given: $\lambda_{H^{+}}^\infty = 350 \ S \ cm^2 \ eq^{-1}$ and $\lambda_{OH^{-}}^\infty = 200 \ S \ cm^2 \ eq^{-1}$.

As the temperature increases,the $pH$ of a $KOH$ solution

Find the concentration of hydrogen ions in a solution with $pH = 5.4$ in $mol/L$.
