Let's assume that both the acid's and conjugated base's concentrations are equal to 6 M. Utilize the equation: pH = pKa + log ( [A⁻]/ [HA]) pH = 6.4 + log (6 M/6 M) pH = 6.4 + log (1) pH = 6.4 + 0 pH = 6.4 The pH of our buffer is equal to 6.4. What buffers are there in human blood? WebbAcetic acid is a relatively weak acid, at least when compared to sulfuric acid (K a = 10 9) or hydrochloric acid (K a = 10 7 ), both of which undergo essentially complete dissociation in water. A number like 1.75 x 10 - 5 is not very easy either to say or to remember. pink house claremore hours
