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

= - [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
