Is this correct? If not can you please tell me what steps I did wrong? Thanks!

The hydrogen ion concentration of milk is about 1.6 x 10^-7 moles per liter. Find the pH.


pH = -log [H+]
pH = -log[1.6 x 10^-7]
pH = -(-7.204119983)
pH = 7.2
The pH balance of the milk is 7.2

  • inorganic chem really - ,

    pH = -log[1.6 x 10^-7]
    = - [log 10^-7 + log 1.6]
    = -(-7) - .204
    = +7 - .204
    = 6.8

    note
    if H+ were exactly 10^-7 it would be neutral
    It is more, so acid
    Therefore the pH must be LESS THAN 7
