pH WORKSHEET
pH—pOH—[H+]—[OH-]
1. Calculate the values of both pH and pOH of the following solutions:
pH
pOH
a. 0.020 M HCl
b. 0.0050 M NaOH
c. A blood sample
7.2 x 10-8M of H+
d. 0.00035 M KOH
2. Find the values of [H+], pOH, [OH-], that correspond to each of the following pH
values:
[H+]
[OH-]
pOH
a. pH of lemon juice = 2.90
b. pH of sauerkraut = 3.85
c. pH of milk of magnesia, a
laxative = 10.81
d. pH of most orange juices =
4.11
e. pH of dilute household
ammonia in windex = 11.61
3. Determine which of the solutions in #2 are acidic?
4. A certain brand of rootbeer has a hydrogen concentration equal to 1.9 x 10-5M.
What is the pH and pOH of this rootbeer?
5. Dr. Pepper has a [H+] = 1.4 x 10-5M. What is its pH?
