Chemistry - Ionic Equilibrium Question with Solution | TestHub

$$\begin{array}{rl}& \mathrm{pH}=-\log \left[{\mathrm{H}}^{+}\right]\\ & \Rightarrow \mathrm{pH}=2\Rightarrow \left[{\mathrm{H}}^{+}\right]\text{for }\mathrm{pH}=2\text{ is }10^{-2}\\ & \mathrm{pH}=6\Rightarrow \left[{\mathrm{H}}^{+}\right]\text{for }\mathrm{pH}=6\text{ is }10^{-6}\\ & \Rightarrow \frac{10^{-2}}{10^{-6}}=10^4=10,000\\ & \end{array}$$
