A careful search of various old solutions sitting around inyour laboratory reveals a 2.870 L solution containing 0.03824 MHBu, where HBu stands for the weak bucolic acid. In order todispose of this solution, the stockroom attendant tells you she must know the pOH of the solution exactly. A quick perusal of the CRC Handbook shows a Ka value of 1.7919x10-13for bucolic acid. What is the pOH of this solution.
