The $\mathrm{pH}$ of a chemical solution is given by the formula $$\mathrm{pH}=-\log _{10}\left[\mathrm{H}^{+}\right]$$ where $\left[\mathrm{H}^{+}\right]$ is the concentration of hydrogen ions in moles per liter. Values of pH range from 0 (acidic) to 14 (alkaline). (a) What is the pH of a solution for which $\left[\mathrm{H}^{+}\right]$ is $0.1 ?$ (b) What is the pH of a solution for which [H $^{+}$ ] is 0.01? (c) What is the $\mathrm{pH}$ of a solution for which $\left[\mathrm{H}^{+}\right]$ is $0.001 ?$ (d) What happens to $\mathrm{pH}$ as the hydrogen ion concentration decreases? (e) Determine the hydrogen ion concentration of an orange $(\mathrm{pH}=3.5)$ (f) Determine the hydrogen ion concentration of human blood $(\mathrm{pH}=7.4)$
