• Acetic acid will freeze when placed in ice. Do not interpret frozen acetic acid
as crystal formation.
• Ligroin will evaporate quickly when placed in boiling water. Cool down your
water bath (by adding ice) before heating a test tube that contains ligroin.
Prepare a table in your notebook before coming to lab in which you will record
your observations. You will need to record the solubility at room temperature, the solubility at elevated temperature, the result of adding water to a solution of the compound (when applicable) and the appearance of the crystals.
