Chapter 4.4, Problem 119AYU

Chemistry The pH of a chemical solution is given by the formula

$pH\text{ =}-{\log }_{10}\left[H^{+}\right]$

Where $\left[H^{+}\right]$ is the concentration of hydrogen ions in moles per liter. Values of $pH$ range from $0$ (acidic) to $14$ (alkaline).

What is the $pH$ of a solution for which $\left[H^{+}\right]$ is $0.1$?

What is the $pH$ of a solution for which $\left[H^{+}\right]$ is $0.01$?

What is the $pH$ of a solution for which is $\left[H^{+}\right]$ is $0.001$?

What happens to $pH$ as the hydrogen ion concentration decreases?

Determine the hydrogen ion concentration of an orange $\left(pH=3.5\right)$,

Determine the hydrogen ion concentration of human blood $\left(pH=7.4\right)$.
