If the hydronium ion concentration is increased, the pH of the
solution decreases.
The concentration of hydrogen ions in a solution expressed usually in moles per
liter or in pH units and used as a measure of the acidity of the solution
indicator dyes for narrow ranges of hydrogen-ion concentration
Answer:
The pH would decrease and the solution would become more acidic
Explanation:
pH of a solution is a measure of its hydronium ion (H3O+) concentration. Mathematically it is given as:
[tex]pH = -log[H3O+] -------(1)\\\\i.e. [H3O+] = 10^{-pH} ------(2)\\[/tex]
It is given that pH of the solution = 2.4
Therefore based on equation (2), the [H3O+] would be:
[tex][H3O+] = 10^{-2.4} = 3.98*10^{-3} M[/tex]
If the [H3O+] concentration were increased then based on equation (1) the pH of the solution would decrease i.e. it would become more acidic.
For example, lets say that the new [H3O+] = 5.0 * 10⁻³ M, then
[tex]pH = -log[5*10^{-3} ] = 2.3[/tex]
