pH of tomato juice is 4.4 . Calculate concentrations of H3O+ and OH- ?

Asked by Deepak Singh | 24 Feb, 2015, 09:39: PM
answered-by-expert Expert Answer

pH = 4.4

pH = - log [H+] = - log [H3O+]

- log [H3O+] = 4.4

log [H3O+] = -4.4

[H3O+] = Antilog (-4.4)

[H3O+] = 3.981 x 10-5

[OH-] = 14 - 3.981 x 10-5 = 13.99
