Developing a Model Airbag Lucy Peng Methods: To begin the experiment‚ my partner and I brainstormed several different airbag model designs: the first model containing a barrier of some sort to separate the NaHCO3 and the CH3COOH (Model 1) and the second model containing a “cup” or “pocket” taped to the wall of the plastic bag that would prevent the reactants form coming into contact (Model 2). We then measured arbitrary amounts of NaHCO3 using plastic weighing boats and an electronic scale.

adding an additional absolute ethanol (2mls). The solution was refluxed for 40 minutes and was removed from the heating plate. Distilled water (30mls) was added to the solution. Sodium bicarbonate (60mls) was added dropwise until the pH was approximately 8. The pH was monitored using pH paper. Adding sodium bicarbonate caused a precipitate of benzocaine to form. The precipitate was filtered out of the solution using vacuum filtration. The precipitate was allowed to dry for recrystallization. The product

The proper chemical name for sodium bicarbonate or baking soda is sodium hydrogen carbonate.{Source 1} What does baking powder contain? It is made from an alkali‚ bicarbonate of soda‚ and an acid‚ cream of tartar‚ plus a filler like corn flour or rice flour which absorbs moisture. {Source 2} How does

reacts with Panacetin to produce the sucrose as an insoluble solid. Aspirin is removed from the solution by reacting with sodium bicarbonate. The aqueous layer reacts with hydrochloric acid‚ the unknown component can then be isolated by evaporating the solvent from the dichloromethane solution. Observations and Data: Aspirin reacted with Sodium Bicarbonate to form salt‚ sodium acetylsalicylate. The reaction caused fizzing and gas. When hydrochloric acid was added to sodium acetylsalicylate

aqueous sodium bicarbonate solution was added to the dichloromethane. A stopper was placed on the separatory funnel and was shaken and pressure was frequently released. The 2 liquids separated into clear layers and the lower layer (dichloromethane layer) was tapped into an Erlenmeyer flask. The aqueous layer was placed into a 400 ml beaker. The dichloromethane was placed back in the separatory funnel. 3. The dichloromethane was extracted with 2 more fresh portions of sodium bicarbonate solution. The
