10-49. How much benzoic acid, Ka = 6.3 X 10-6, will remain

undissociated in the aqueous phase of a 50%oil-water emulsion ifthe

initial concentration of benzoic acid in the aqueous phase is 0.5%? The

aqueous phase is buffered at pH 5 and the oIw partition coet1iclent =

6.33. Assume that benzoic acid remains as a monomer in the oil phase.

during longer space exploration trips, crewmembers may develop vision impairment risks and short-term cardiac atrophy or a decrease in the size, strength, weight, and activity of the heart during space flight because they can experience microgravity. in addition, the long-term medical condition is loss of bone mineral density and radiation exposure.
