You need to make 150.0 mL of a 0.10 M NaCI solution. You have solid NaCl, and your lab partner has a 2.5 M NaC1 solution. Explain how you each independently make the solution you need.
6-22 Answer true or false. (a) Water is a good solvent for ionic compounds because water is a polar liquid. (b) Small covalent compounds dissolve in water if they can form hydrogen bonds with water molecules. (c) The solubility of ionic compounds in water generally increases as temperature increases. (d) The solubility of gases in liquids generally increases as temperature increases. (e) Pressure has little effect on the solubility of liquids in liquids. (f) Pressure has a major effect on the solubility of gases in liquids. (g) In general, the greater the pressure of a gas over water, the greater the solubility of the gas in water. (h) Oxygen, O2, is insoluble in water.

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…
