Hello everyone.
00:01
Let's start the question.
00:03
Here in this question we have to mention the precautions which are recommended while we are working in a chemistry laboratory.
00:10
So the first part of the question is what is the need, why we are wincing the glassware with organic solvents after the experiment.
00:17
So basically what happens is most of the organic chemicals, most organic chemicals, most organic chemicals which are available in the lab do not dissolve.
00:32
In water.
00:34
They do not dissolve in water.
00:39
So in order to remove them completely from the glassware, it is being mentioned, it is being asked to rinse the glassware with organic solvent so that it may eliminate the possibility of error in the experimentation result.
00:55
Let's now move on to the second part of the question in which we have to mention the reason, we have to mention the precaution, why we are performing.
01:03
The procedure in a fume hood.
01:06
So what happens is when we are working with few chemicals, most organic chemicals, most organic chemicals contains, they involve harmful vapors, involves harmful vapors.
01:27
That is the reason it is being performed...
