Answer:
[tex][H_{3}O^{+} ] = 10^{-2}[/tex] mol/ L
Explanation:
Measure of [H₃O⁺] , i.e hydrogen ion concentration, indicates the acidity of the solution. The greater the concentration, the greater is the acidity. [H₃O⁺], this quantity can range from 10⁻¹ to 10⁻¹⁴ at ambient temperature(298K). This range is always temperature dependent.
Measure of acidity of a solution is expressed more conveniently using the notation of pH.
[tex]pH = - log_{10}[H_{3}O^{+} ][/tex]
Using the above formula
[tex][H_{3}O^{+} ] = 10^{-(pH)}[/tex]
[tex][H_{3}O^{+} ] = 10^{-2}[/tex] mol/ L
