Caution
The demonstration on this page shows a technique that should not be used by undergraduate chemistry laboratory students.
There is no sound with this movie.
The student is trying to dissolve a solid in the volumetric flask. He should have dissolved the solid in a beaker first and then added the solution to the volumetric flask. Had he used a beaker, he could have heated the solution on a hot plate, which would have helped dissolve the solid more quickly.
