A solution-phase reaction is carried out under controlled conditions so that the amount of one reactant can be determined with high precision. An indicator is added to titration to indicate when the reaction is complete. a O b с Od о The amount of product that would result if all the limiting reagent were reacted are called percentage yield. Percentage yield can be calculated by the ratio of actual yield to the theoretical yield times 100. a b C

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
