a. A 1 liter solution contains 0.509 Mhypochlorous acid and 0.382 Mpotassium hypochlorite.
Addition of 0.191 moles of hydroiodicacid will:
(Assume that the volume does not change upon the addition ofhydroiodic acid.)
Raise the pH slightly
Lower the pH slightly
Raise the pH by several units
Lower the pH by several units
Not change the pH
Exceed the buffer capacity
b. A 1 liter solution contains 0.246 Mhypochlorous acid and 0.328 Mpotassium hypochlorite.
Addition of 0.271 moles of sodiumhydroxide will:
(Assume that the volume does not change upon the addition ofsodium hydroxide.)
Raise the pH slightly
Lower the pH slightly
Raise the pH by several units
Lower the pH by several units
Not change the pH
Exceed the buffer capacity
