What are the formulas of the salts that precipitates when ...

Aqueous sodium bicarbonate was used to wash the crude n-butyl bromide. (a) What was the purpose of this wash? Give equations, (b) Why would it be undesirable to wash the crude halide with aqueous sodium hydroxide? Look up the density of n-butyl chloride (1-chlorobutane). Assume that this alkyl halide was prepared instead of the bromide.

What are the formulas of the salts that may precipitate ...

The purpose of this wash is to prevent the formation of polybrominated butanes from addition of any more bromine to the 1- bromobutane. The bicarbonate reacts with the unreacted bromide to form Co 2 and sodium bromide which is an inert salt. The washing with sodium bicarbonate will then remove the acid from the aqueous phase.
