A watch glass with some ice cubes on top of the Erlenmeyer flask allows you to gently reflux the mixture less solvent evaporates away during the heating phase. The first step of recrystallization is a solvent selection procedure based on properties like. Recrystallization Part Ii Briefly explain how to do TLC. . The criteria used to choose an appropriate recrystallization solvent includes. What is meant by reflux and what purpose does it serve. How do you determine how much solvent to use in a recrystallization. What are the properties of a perfect recrystallization solvent. Place about 50 mg of the sample in a test tube. Moreover it is desirable that the boiling points of the two solvents should be. Depending on its molecular structure a solute can be classified as soluble partially soluble or insoluble in these solvents or solvent mixture. A finding a solvent with a high temperature coefficient. A good r...
