Title: Combining Vinegar and Baking Soda

Statement of Problem: We wanted to observe what kind of reaction would take place when combining white vinegar and sodium bicarbonate (baking soda).

Equipment or Apparatus: Sodium Bicarbonate (baking soda), white vinegar, 13 oz. vessel, cork, household measuring devices (for lack of a scale) such as glass measuring cup and metal measuring spoons, and safety goggles.

Procedure: We selected a vessel and a cork that loosely fit in the top of the bottle for our experiment and placed it on a hard flat surface. One student measured ½ tsp. baking soda into the bottom of the vessel. The vessel was placed on the floor and tipped at an angle. One ounce of vinegar was added as quickly as it could safely be poured into the bottom of the vessel. When the vinegar was completely poured the cork was placed into the top of the bottle. The first trial represented a weak presence of carbon dioxide gas. The solution bubbled up, the solid dissolved completely, and the cork remained stationary in the top of the bottle. A second trial was done and the variable that was modified was the amount of baking soda measured into the vessel. The amount of baking soda added was increased from ½ tsp. to ¾ tsp. and the amount of vinegar stayed the constant at 1 ounce. The second trial displayed similar results of a weak presence of carbon dioxide. The solution bubbled up, the cork stayed stationary in the top of the bottle, but the solid did not dissolve completely. A third trial was performed in which we decided to increase the amount of vinegar used. The indicator which triggered this decision was the resulting solid at the bottom of vessel. In the third trial we kept the baking soda our constant at ¾ tsp. and added 2 ounces of vinegar. The results remained similar to trial two. The solution bubbled, the cork remained stationary in the top of the bottle, and there remained solid in the bottom of the...
