According to the given question, first we have to consider the reactions of carbon dioxide and then…

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. After the gas has bubbled through the water for a few minutes (so that it may be assumed the solution is saturated with the gas), test the acidity of the solution by adding 1 drop of universal indicator solution and check the pH on the colour chart provided. Record your observations onto your results page. RESULTS (Remember to not include spectator ions in ionic equations.) Part A - Reactions of Carbon Dioxide Gas 2. 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 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 cach. Observations end of step 1. 3.

Add 20 ml of 2 M NAOH to the water in the 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.
