based upon the limiting reactant, as no additional product can be formed once it has been used up. The limiting reactant is related to the product using the stoichiometry of the balanced equation. In the example above, since Cl2 is the limiting reactant and it could form 188.1 g of AlCl3 product, that will be the theoretical yield for the reaction.

Once the students complete the lab, a guided discussion of their results helps reinforce the concept of a limiting reactant. Have the students reach a consensus on which well in each reaction produced the maximum amount of precipitate. In these wells, the reactants should be in the same ratio as the coefficients in the balanced equation.

As a result there is a limited amount of carbon dioxide gas that can be produced. When smaller amounts of sodium bicarbonate are added, it is the limiting reagent and the acetic acid is the excess. When the moles of sodium bicarbonate exceed the moles of acetic acid, the designations switch and acetic acid becomes the limiting reactant.

In scientific terms, we can say that reactant B is the limiting reagent. In other words, no matter how much A is added, no more product is made when B is consumed—reactant B limits how much product is obtained. On the other hand, reactant A is called the excess reagent because there is more than enough of reagent A.
