Summary
An excess reactant is a reactant in a chemical reaction with a greater amount than necessary to react completely with the limiting reactant.

Summary
An excess reactant is the reactant in a chemical reaction with a greater amount than necessary to react completely with the limiting reactant. It can be identified using the balanced chemical equation, which gives the mole ratio between reactants. Solubility and excess reactant can also be taken into consideration, as the reaction involves one or more reactants with low solubility in a solvent.

Summary
In a chemical reaction, reactants that are not used up when the reaction is finished are called excess reagents . The reagent that is completely used up or reacted is called the limiting reagent , because its quantity limits the amount of products formed.
