Excess reactants reactants not completely consumed in a reaction. Theoretical yield the amount of a product that can be made from the limiting reactant. Theoretical yield the amount of product that would result if all the limiting reactant reacted. Actual yield the amount of product actually obtained from a reaction. The component of the solution that changes state is called the solute. The component that keeps its state is called the solvent.
