Limiting reactant experiment lab report by connectioncenter.3m.com . For this experiment, the reaction is between sodium carbonate, N a 2 C O 3 and, The colour of products obtain is white solid of calcium. One way of finding the limiting reagent is by calculating the amount of product that can be formed by each reactant; the one that produces less product is the limiting reagent. If the reactants are not mixed in the correct stoichiometric proportions (as indicated by the balanced chemical equation), then one of the reactants will be entirely consumed while another will be left over. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Using this equation we were able the find the %mass which was 90.3%. 4 RESULT AND OBSERVATION 3. 2 Pages. 0000005869 00000 n
