The Mass and Percent Yield Lab Report is submitted to understand the reaction between sodium hydrogen carbonate and sulfuric acid. As the Background of this Percent Yield Lab Report suggests, in this experiment, one will react a known mass of sodium hydrogen carbonate (NaHCO3) with an excess of sulfuric acid (H2SO4) to produce sodium sulfate (Na2SO4), Carbon Dioxide (CO2), and Water (H2O). To find the results, one will then calculate the theoretical yield of the carbon dioxide gas and then determine the percent yield for the reaction. As the lab report depicts here, apart from Background, you can have Purpose, Apparatus & Materials, Procedure, and the image illustrating the chemical reaction.
