WebA buffer system is a solution that resists a change in pH when acids or bases are added. The skin possesses a fairly high buffer capacity, which is determined by the amount of H + or OH-ions that is needed until the pH value of a solution changes by the unit 1. Buffers contain a weak or medium strong acid (base) and the corresponding salt. WebNov 14, 2024 · For every mole of HBr, there will be 1 mole of H +, so the concentration of H + will be the same as the concentration of HBr. Therefore, [H +] = 0.025 M. pH is calculated by the formula. pH = - log [H + ] To solve the problem, enter the concentration of the hydrogen ion. pH = - log (0.025) google play france television
