When heating a flammable or volatile solvent for a recrystallization, which of these statements are correct? More than one answer may be correct.

1) You should not use an open flame to heat the solvent.

2) You should heat the solvent in a stoppered flask to keep vapor away from any open flames.

3) You should ensure that no one else is using an open flame near your experiment.

A volatile substance is defined as the substance which can easily evaporate into the atmosphere due to weak intermolecular forces present within its molecules.

Whereas a flammable substance is defined as a substance which is able to catch fire easily when it comes in contact with flame.

Hence, when we heat a flammable or volatile solvent for a recrystallization then it should be kept in mind that should heat the solvent in a stoppered flask to keep vapor away from any open flames so that it won't catch fire.

And, you should ensure that no one else is using an open flame near your experiment.

Thus, we can conclude that following statements are correct:

You should heat the solvent in a stoppered flask to keep vapor away from any open flames. You should ensure that no one else is using an open flame near your experiment.
