1. A liter of milk has a [H+] of about 2. 51 x 10-7. (You may prefer to think of the hydronium ion

concentration, [H30'], as 2. 51 x 10-7. ) Use the formula

for the calculation of pH provided and show each step

as you calculate the pH of milk. In order to get full

points you must show all the steps you take.

You encounter a solution that is acidic and you decide to test it by adding a small amount of a strong acid. the ph lowers slightly but is approximately unchanged, and still remains acidic. what can you say about the solution? a. it is a buffer solution. b. it is not a buffer solution it is a strong acid solution. d. the solution has been neutralized. e. the solution has excess acid present
