If a 0.135 g sample of NaCl were placed on an ion exchange column in the H+ form and the eluate titrated with 0.1231 M NaOH, what volume of the NaOH solution would be required to reach a phenolphthalein end point?
Neither serine nor leucine are eluted from the column because the pH of the elution buffer is too high. D. Leucine will elute first, followed by serine. E. Serine will elute first, followed by leucine.
