Write about the relation of $pH$ and the concentration of $H_3O^+$ and $OH^-$ in acidic,basic,and neutral solutions.

(N/A) The relationships are as follows:
$1$. Neutral solution: $[H_3O^+] = [OH^-] = 1 \times 10^{-7} \ M$ and $pH = 7.0$.
$2$. Acidic solution: $[H_3O^+] > [OH^-]$,$[H_3O^+] > 10^{-7} \ M$,$[OH^-] < 10^{-7} \ M$,$pH < 7.0$ and $pOH > 7.0$.
$3$. Basic solution: $[H_3O^+] < [OH^-]$,$[H_3O^+] < 10^{-7} \ M$,$[OH^-] > 10^{-7} \ M$,$pH > 7.0$ and $pOH < 7.0$.
