the club. A consumer agency that wanted to check this claim took a
random sample of 36 members of this health club and
found that they
lost an average of 9.2 pounds within the first month of membership
with a population standard deviation of 2.4 pounds. Find the

n a Laboratory, you have the following chemicals available:
1.0 M NaOH, 1.00 M HCl, 1.00 M H3PO4, NaH2PO4 (s), Na2HPO4 (s), and Na3PO4 (s).
Describe TWO ways of making 1000 mL of a buffer of pH = 12 (Use only the above
chemicals, plus distilled water.)
[Given: H3PO4 - Ka1 = 6.9 x 10-3
; NaH2PO4 - Ka2 = 6.2 x 10-8
; Na2HPO4 - Ka3 = 4.8 x 10-13
