1) Calculate the [H] in a HC102 solution that has a pH of 3.78.

1.6 X M is the [H] in a HC102 solution that has a pH of 3.78.

Explanation:

Given:

pH of the acid = 3.78

[H+] ion concentration = ?

The dissociation of the acid is shown as:

+ ⇔ HClO2

however, weak acid like HClO2 does not dissociate or ionize completely which causes low hydrogen ion release in the solution.

pH is calculated by applying the formula:

pH = - log [H+]

To calculate the H+ ion concentration the equation will be expressed as:

[H+] =

       =

       = 1.6 X M

The concentration or molarity of the Hydrogen ion in the solution of the acid is  1.6 X M.
