In a wet lab you will separate the solid aspirin from the liquid via gravity filtration. What must you do to ensure that you lose minimal product during the filtration?
In a wet lab, what sort of safety concerns are valid when using a hot plate for a water bath?
What are you using to recrystallize the aspirin? You must use a solvent in which the aspirin is soluble at high temperature but much less soluble at room temperature. But that seems such an obvious answer that I don't know if that addresses the question or not. For #2, again I don't know what you are using as a solvent but you don't want the fumes of a volatile solvent (ether or such) to come in contact with the hot plate. In order to answer these questions we really need to see the complete procdure.
