4. Carbon Dioxide w. PART I i. Put 0.5 to 1.0 mL of limewater into a well in your plate. ii. Take your baking soda and place ½ teaspoon in the bottom of a generation test tube. iii. Hold the test tube over your pie tin and add ½ pipet of white vinegar to the baking soda. The reaction will cause an overflow, but as soon as the overflow stops, insert the stopper with the copper and plastic gas delivery into the test tube. iv. Place the open end of the copper and plastic gas delivery tube into the limewater you just poured into your well plate. v. Observe your reaction. x. PART II vi. Put 0.5 to 1 mL of bromothymol blue into another well of the plate. vii. Rinse the gas tubing under running water in the sink and set up another test tube with baking soda and vinegar just like part I. viii. When the assembly is complete, place the open end into the bromothymol blue. Observe the reaction, and record your results. ix. Light a toothpick or a match and insert the flame into the top part of the gas generation test tube. x. Record what you observe. y. PART III xi. Take the chemicals from the parts above and dump down the sink and flush with water. Rinse and clean the test tubes and equipment to be reused later. xii. Put 0.5 to 1 mL of limewater into another well of the
