Determination of the Percent Yield of Sodium Acetate When a Chemical Reaction with Sodium Bicarbonate Occurs
Determination of The Percent Yield of Sodium Acetate When a Chemical Reaction with Sodium Bicarbonate OccursDesign Introduction The purpose of this lab is to determine the percent yield of a chemical reaction between sodium bicarbonate (baking soda) and acetic acid (vinegar). When the two products reacted together, a double replacement occurred. This then changed to dihydrogen monoxide, carbon dioxide, and sodium bicarbonate, otherwise known as the products.  One way that we purified the sodium acetate was by boiling away the water.  Another way we could have purified it is by filtration; this process works by getting a “cloth or a membrane” so that it allows the liquids to facilitate through.  And since this is a balanced chemical equation, it’s easy to find the percent yield. To find the percent yield, you use three conversion factors for each reactant to change to the product that you want; in this case, we are looking for the percent yield of sodium acetate. In the first step, you covert the mass of one of the reactants to moles using molar mass.  Next, you use the mole to mole ratio to convert to sodium acetate.  Then, you change to grams using molar mass again. After you have done these steps for both reactants, you compare the two numbers. Whichever number is smaller is the theoretical yield.  The limiting reagent is the reactant at was associated with the theoretical yield and the other reactant is excess.  Finally, you take how much sodium acetate was made and divide that number by the theoretical yield and multiply by 100.  This gives you the percent yield and according to the law of conservation of mass, we can expect our percent yield to be less than 100 percent, for “matter cannot be created or destroyed”.  Supported by this statement, our percent cannot be a negative number either.  This is how we can determine if a percent yield is correct or incorrect.
