Grignard Reaction Experiment Part 2, Forming Phenylmagnesium Bromide

This organic chemistry lab video describes an experiment where phenyl Grignard reagent is formed from bromobenzene and magnesium metal and then subsequently treated with solid carbon dioxide (CO2) and aqueous acid to synthesize benzoic acid. This product is then separated from a biphenyl impurity using a series of acid-base extractions. The resulting purified benzoic acid is then characterized by IR spectroscopy and melting point analysis. This is the second video in the series and focuses on forming the Grignard reagent, phenylmagnesium bromide.

As the pandemic is still going, I do not have in-person lab and your video help me a lot to understand the procedure, thank you for your work.

If the ether is not dry, could you dry it with that calcium sulfate from before or molecular sieves and such?
