. This reaction is followed by addition of excess sodium borohydride in small portions
. The reaction mixture is left for 10 minutes and heat is then applied to the reacting mixture. Therefore for safety purpose, during heating, the lids should not be put back on the waste containers because the reaction waste is still generating hydrogen gas that would get trapped in the container.
The reacting mixture is then poured into a beaker of ice water afterwards and Vacuum filtration and blotting dry is used to collect the precipitate instead.
