Ph of oh- 1x10-8
WebThe pOH of a solution is defined as the negative log10 [OH¯] Conversely, [H3O+] = 10-pH and [OH¯] = 10-pOH The pH of a neutral solution is therefore 7. (-log [1 x 10 -7] = 7) The sum of the pH and pOH must always equal 14. This is because the –log K W = -log (1 x 10 -14) = 14. More generally, acid dissociation constants (K a) are of the form: WebJun 10, 2024 · The concentration of Hydrogen ion and hydroxide ion are related with the following formula: [H+] x [OH-] = 1x10^-14 [H+] x 1x10^-8 = 1x10^-14 Divide both side by 1x10^-8 [H+] = 1x10^-14 / 1x10^-8 [H+] = 1x10^-6M 4. Data obtained from the question include: pOH = 9 Hydrogen ion concentration, [H+] =..? First we shall determine the pH.
