Materials Needed solid I2 solid CUSO4-5H20 food dye solid (NH4)2SO4 heavy metals waste container halogenated waste container non-halogenated waste container semi-micro test tubes and rack regular test tubes and rack squash pipettes acetone cyclohexane propan-2-ol Method Part A: Solubility of ionic and molecular solids 1. Place a small amount (about the size of 1 grain of rice, see picture) of copper sulfate into each of three DRY semi-micro test tubes. Add 20 drops of water to the first test tube and gently flick the test tube with your finger to ensure mixing. 2. Repeat step 1 using acetone in place of water as the solvent in the second test tube. 3. Repeat step 2 replacing acetone with cyclohexane in the third test tube. Hold the test tubes against a white background to compare the solubility of copper sulfate in the three solvents and record your results. Discard these mixtures into the heavy metals waste container in the fume cupboard. Once these test tubes have been emptied you…

Which of the following statements is correct? (Choose all the apply) The more hydroxyl (OH) groups on an alcohol, the less soluble it is in water. Gas solubility increases as the partial pressure of the gas (over the solvent) decreases. Gases are less soluble in water as the temperature increases. Most solids increase their water solubility with decreasing temperature. The solubility of liquid alcohols in water decreases as the number of carbon atoms in the alcohol molecule increases.
