Baking Soda Stoichiometry

I researched many things about my experiment before doing it. This way, I could have a better idea of what to look at while conducting the experiment. I completed background research on baking soda and vinegar, CO2 production from their reaction, base and acidic substances reacting, and stoichiometry of baking soda and vinegar reactions. After doing research, I found many interesting facts and information. First I researched vinegar. It is an alcoholic liquid that has been allowed to sour. Vinegar is acidic; it has a pH of 2-3 (Decelles 2002). Then, I researched about baking soda. Baking soda is white powder that is used for cooking and cleaning. Baking soda is a base; it has a pH of 9 (Decelles 2002). When baking soda and vinegar are combined, it produces carbon dioxide …show more content…
Carbon dioxide is the main gas we exhale. This gas consists of one molecule of carbon and two molecules of oxygen. I also did research on the reaction of base and acidic substances. I learned that when we combine vinegar and baking soda, it produces carbonic acid; it then decomposes into carbon dioxide and water because it is unstable. Then, carbon dioxide pushes the remains of the reacted carbonic acid and vinegar out of the bottle (MrChemistryGeek 2012). Finally, I researched the stoichiometry of baking soda and vinegar reacting. Mr. Kivimaki stated, “The stoichiometry of my reaction (or any reaction) will allow you to predict the amount of product (CO2) based on the amounts of the reactant. So if one knows the amount of moles for baking soda and the amount of moles for vinegar, you can predict the amount of moles for CO2 produced. Then the molar amount can then be converted to volume of gas.” Those were some of the things that I researched to get a better understanding on my
