Determine the pH of solutions with each of the following [H3O+]
a. 2.0 x 10^5 M
Not asking for just the answer but how to do it
a. 2.0 x 10^5 M
Not asking for just the answer but how to do it

pH = log([H3O+])
pH = log(2.0x10^5)
pH = 4.70
pH = log(2.0x10^5)
pH = 4.70

Take the negative log of the concentration of H3O+.
pH = log([H3O+])
pH = log(2.0x10^5)
pH = 4.70
pH = log([H3O+])
pH = log(2.0x10^5)
pH = 4.70

The guy above me is right
