benzoic acid c6h5co2hhbz solutions are sometimes used in experiments to determine the molarity of a basic solution of
We had this experiment where we took 4-bromo-N-ethanoylbenzeneamine and we refluxed it with HCl to achieve hydrolysis. We then added enough NaOH to render the solution pH 8. We then distilled the mixture in steam to yield 4-bromoaniline. Why was t..
