Butyric acid (CH3CH2CH2COOH = HBt; MW = 88) is a particularly malodorous acid (found in rancid butter, parmesan cheese, and vomit (yuk!), and is also the cause of some body odor). Humans can detect the smell of HBt at concentrations of about 10 ppm in the atmosphere. Typically the way we minimize odor problems is to ensure that most of the butyric acid (TOTBt = [HBt] + [Bt-]) in the water is in the ionized form (i.e., Bt-). The total concentration of butyric acid (TOTBt) in a water sample is 1,000 mg/L as HBt and the pH = 5.5. What is the concentration of HBt in this water in mg/L? The following may be useful in solving this problem: HBt ? H+ + Bt- pKa = 4.82
