Explain how use of 3 M HCl(aq) could separate it from the other components. To do so: show how acid would change the molecule; identify the phase in which this new species would be isolated in a separatory funnel and explain why it would be found there; and suggest when in the sequence of steps you actually performed, HCl could be used to isolate 4-nitroaniline from the other three components.
