Nhi Vu General Chemistry Agnes Rafoulko Recrystallization and Melting Point Determination Introduction : In this experiment, our objective is to determine the melting point of a recrystallized unknown chemical. Using this information, we must then determine its identity by comparing this temperature with the melting points of known chemicals. Chemical Responsibility : It is imperative that we wear our safety goggles at all times. The chemicals we are interacting with may irritate or be toxic by ingestion. Accordingly, we must wear gloves when handling directly with the chemicals. We must remember to dispose our filter paper into the beaker labeled “used filter paper,” dispose of our filter paper in the Buchner funnel in the beaker labeled “used filter paper,” dispose of the liquid in our filter flask down the drain, dispose of our crystals in the “waste experiment 2 crystals” beaker, dispose of our plastic boats into the plastic boats beaker, and dispose of our capillary tubes into the capillary tubes beaker.
