Vedclass · Answer

(A) In pure water or a neutral aqueous solution at $25^{\circ}C$,the concentration of hydronium ions $[H_3O^+]$ is equal to $10^{-7} \ M$.An acidic solution is defined as a solution where the concentration of hydrogen ions (or hydronium ions) is higher than that of a neutral solution.Therefore,for an acidic solution,$[H_3O^+] > 10^{-7} \ M$.Since $pH = -\log[H_3O^+]$,a higher concentration of $[H_3O^+]$ results in a $pH$ value of less than $7$.

In an acidic aqueous solution,the value of $[H_3O^+]$ is $.......$.
