Camphor is reduced to isoborneol by sodium borohydride in ethanol. The instructions for safe disposal of the chemical waste generated by this reaction state that the lids should not be screwed back onto the waste containers. Why should the lids not be put back on the waste containers?

A) The reaction waste is still generating hydrogen gas that would get trapped in the container.

B) Allowing the volatile waste to evaporate will lower the cost of chemical waste removal.

C) Leaving the lid off allows the layers within the container to separate from one another.

D) The tag on the container that lists its contents cannot be read properly when the lid is on.

A) The reaction waste is still generating hydrogen gas that would get trapped in the container.

Explanation:

The issue of garbage and chemical waste is an environmental problem that has attracted attention. Both for the quantity and for the question of how to treat it. This issue is especially important when we think about the issue of chemical residues that, if not disposed of correctly, endanger people's health and the environment.

The subject is so important that there is specific legislation that deals with the subject. Some materials, depending on their characteristics, can cause contamination, corrosion and even combustion. Therefore, there are regulations that regulate the correct way to safely dispose of chemicals.

In the case of chemical residues generated by the reaction produced when the camphor is reduced to isoborneol by sodium borohydride in ethanol, it must be disposed of according to the manufacturer's instructions, to avoid accidents and contamination. In this case, the manufacturer states that the lids should not be screwed back into the waste containers, because the reaction waste is still generating hydrogen gas that would be trapped in the container.
