the test tube and utility clap assembly onto a ring stand. Add about 20 drops of methyl alcohol, methanol, and a boiling chi (boileezers) to the test tube, and place into the hot water. Suspend the thermometer to about 1 cm above the liquid. After the alcohol begins to boil in the test tube, record the boiling pint temperature (+-0.5 C) when the alcohol drops from the tip of the thermometer. B. Boiling Point Boiling point of methyl alcohol 76.0 º C Boiling point of unknown 78.0 º C c. Solubility of solid in water Add 20 drops of Dl mater into two test tubes. Drop a copper sulfate crystal into one test tube, and calcium carbonate into the other test tube. Carefully shake the test tubes and observe whether the solids are soluble or insoluble in water. Solubility of solid in water Copper Sulfate Crystal in water Soluble Calcium carbonate in water Insoluble d. Solubility of a liquid in water
Add about 20 drops of DI water into two test tubes. Then add a few drops of methyl alcohol to one test tube, and into the other add a few drops of amyl alcohol. Shake the test tubes briefly to mix the liquids. Determine whether each liquid is soluble (miscible) or insoluble (immiscible) in water.
