aspirin which is insoluble in water. The aspirin will precipitate out of the aqueous solution and can be collected by filtration. To recover the unknown solid, the dichloromethane will be evaporated under reduced pressure, using a rotovap (short for rotary evaporator). The rotovap works under reduced pressure (partial vacuum) which reduces the

The Rotary Evaporator

The Rotary Evaporator It is commonly taught in General Chemistry classes that the vapor pressure of a liquid or solid varies directly with temperature, i.e., the higher the temperature of a substance, the higher its vapor pressure. When a liquid is heated it begins to boil as the liquid turns to vapor forming

This experiment was conducted to study the effect of temperature on the rate of evaporation of milk solution. The experiment result was taken after 10 minutes gap. The temperature was manipulated at 30⁰C, 50⁰C, 70⁰C and 90⁰C. From observation, at 30⁰C and 50⁰C, there is no presence of condensate in the receiving flask.
