I would be a star in all sports. I can’t just choose one thing to be good at. There are so manny things to choose from, so if I could be anything, I would be them all. For training I would work out and do all of my favorite things. I can’t be limited to exercise for training.
Answer:
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.
Explanation:
Camphor is reduced to isoborneol by dissolving camphor in ethanol in erlenmeyer flask
. 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.
