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
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
