A lab prepares a 1.0 L buffer for cell culture using NH4+/NH3\mathrm{NH_4^+/NH_3} with pKa=9.25pK_a=9.25. The buffer is adjusted to pH 7.25. The concept being tested is buffer composition far from pKapK_a. Which statement best describes the relative amounts of NH4+\mathrm{NH_4^+} and NH3\mathrm{NH_3} at pH 7.25?
