To determine the limiting reactant in the vinegar lab, you would need to compare the amounts of each reactant (vinegar and baking soda) used in the reaction to see which one was completely used up first. The reactant that is completely consumed first would be the limiting reactant.
The Limiting Reactant is the reactant that runs out first in a reaction.
The theoretical yield of a reaction is determined by the limiting reactant because this reactant is completely consumed in the reaction, and the amount of product that can be formed is limited by the amount of the limiting reactant available. Any excess of the other reactant does not contribute to the formation of additional product beyond what is possible with the limiting reactant.
The reactant that is present in the smallest quantity or in a stoichiometric ratio below the required amount will give the lowest yield by limiting the amount of product. This reactant is referred to as the limiting reactant, as it determines the extent of the reaction based on its availability.
The limiting reactant in chemistry is the reactant that is completely consumed in a chemical reaction, limiting the amount of product that can be formed. It determines the theoretical maximum amount of product that can be produced in a reaction. The amount of product formed is dictated by the amount of the limiting reactant present.
If the masses of the reactants are the same, you need to compare the moles of each reactant to determine the limiting reactant. The reactant that has the smallest number of moles is the limiting reactant.
