Answer:

pH [tex]= 1.853[/tex]

Explanation:

For every mole of hydrochloric acid, one mole of hydronium ion is required. Thus, in order to neutralize 0.014 moles of HCL, 0.014 moles of hydronium is required.

[tex][H_3O^+] = [HCl] = 0.014[/tex]

pH  [tex]= -log [H^+] = -log [H_3O^+][/tex]

Substituting the available values in above equation, we can say that   the pH of the solution is equal to

[tex]- log (0.014)[/tex]

pH [tex]= 1.853[/tex]

pH of a [tex]0.014[/tex] M HCL solution [tex]= 1.853[/tex]
