(6pts) Reaction F - Reaction of Sodium Hydrogen Carbonate, NaHCO3(s), with Hydrochloric Acid, HCl(aq) Use the video provided below to make your observations virtually. If you have technical issues with the virtual data, please contact support. From the procedure 1. Add about 4 mL of 3 M HCI to a 50-ml beaker (not larger). 2. Obtain a watch glass. Add a small scoop of solid NaHCO3 to the beaker and immediately cover it with the watch glass. This will contain the gas until you are ready to test it. Record your observations. 4. As soon as the reaction settles down: light a wooden splint, remove the watch glass, and lower the lit end of the splint down into the gas in the beaker. DO NOT dip the splint into the solution. 5. Record your observations. 6. Light a wooden splint and hold it next to the top of the test tube. 7. Remove the paper towel plug and immediately move the lit end of the splint into the top of the test tube. Do not dip the splint into the solution. 8. Record what happened to the flame. The video below shows the result of adding HCI to NaHCO3. In addition to the observations in the video, note that the solution became quite warm during the reaction. When the burning splint was brought towards the top of the test tube, the flame was extinguished. For a text description of the video, click here.

1. Fill a medium-to-large size test tube about one fourth (1/4) full of water and place the test tube in your test tube rack. 2. Using forceps, obtain a small piece of calcium metal. Make sure it's hard and metallic gray and not white and crumbly. 3. Add it to the water and allow it to stand for a few minutes. (If it starts to froth up to the top of the test tube, try testing the froth with a lit wooden splint.) 4. When the reaction subsides, test the mixture with a piece of red litmus paper or pH paper. 5. Record your observations. 6. Record all of your observations. The image below shows the result of adding Ca to H₂O. In addition, the solution became warm after adding Ca. The reaction mixture turned red litmus paper blue.
