Hypochlorous acid >
Acid= HClO
Salt = NaClO
(Ka= 3.0 x 10^-8)
Hypobromous acid > Acid=HBrO
Salt =NaBrO
(Ka= 2.5 x 10^-9)

1. How many milligrams of hypochlorous acid ( HClO ; Ka = 3.0 x 10-8) must be in a 3.0-L solution that has a pH of 6.52?

2. A buffer solution of pH 7.6 is to be prepared using HClO and NaClO, If the concentration of the acid is to be 0.50 M, what should be the concentration of its conjugate base?

3. A buffer solution with pH 8.5 is to be prepared from among the three Acid-Sodium salt pairs above..
