Chapter 19: Problem 136
A biochemist needs a medium for acid-producing bacteria. The \(\mathrm{pH}\) of the medium must not change by more than \(0.05 \mathrm{pH}\) units for every \(0.0010 \mathrm{~mol}\) of \(\mathrm{H}_{3} \mathrm{O}^{+}\) generated by the organisms per liter of medium. A buffer consisting of \(0.10 \mathrm{M}\) HA and \(0.10 \mathrm{M} \mathrm{A}^{-}\) is included in the medium to control its \(\mathrm{pH}\). What volume of this buffer must be included in \(1.0 \mathrm{~L}\) of medium?
