A question based on solubility of CO2, which is to be accomplished.

Part A - Reactions of Carbon Dioxide Gas 1. Place a small lump of dry ice into a large test-tube. To the dry ice add about 5 mL of water.

Record SODLM HYDROXIDE your observations onto your results page. Place two large test tubes in the test tube rack. In one tube place a small lump of dry ice and cover the mouth of the tube with a loose plug of cotton wool. Stand the test tube in a beaker of containing a little warm water (from the hot water 2. tap) for a minute. The test tube will fill with carbon dioxide gas. In the meantime, obtain two small (100 or 150 mL) beakers, and place 20 mL of water in each and add 3 drops of universal indicator to each. 3. Do this step quickly to avoid loss of CO>(g) from the test tube. Remove CO,(g) |CO,(g) the cotton wool and tilt the test tube to allow the dry ice to slide into the second test tube and invert the first tube into one of the small beakers containing water (see adjacent figure). Transfer the cotton wool plug to the second test tube which should now have the solid CO2 in it. 4. Warm the second tube in warm water for a minute, then remove the cotton wool, let the CO,(s) slide out into an empty beaker and invert the tube into the second small beaker. Add 20 mL of 2 M NaOH to the water in the SODIUM HYDROXIDE 2M second beaker and carefully move the test tube around to stir the solution (see adjacent figure). H,O(1) NaOH(aq) 5. Observe both test tubes over a 10 minute period, noting any changes in the liquid level in the two test tubes.
