WebDiethyl ether is the first solvent added to the biphenyl/benzoic acid mixture. Tends to be volatile→ goes from liquid to gas more readily; thus, this step performed in the fume hood. ... Mixed solvent recrystallization is the process of using _____ solvents b/c sample is ↑ soluble or ↓ soluble in both hot and cold solvent. "Good" solvent= WebPlace about 50 mL of water in a 150 mL beaker, and heat it to boiling on the hot plate. In a medium test-tube, add a small amount (size of a pencil eraser) of solid, and 1-2 mL of solvent. If it dissolves in cold solvent, it won’t work, so try another solvent. If it doesn’t dissolve in the cold solvent, heat the test-tube up. the kam people of china
