What is Limiting Reagent?
The reactant that is completely consumed in a chemical reaction, limiting the amount of product that can be formed. Once the limiting reagent is exhausted, the reaction stops. The theoretical yield of product is calculated from the moles of the limiting reagent.

Limiting reagent analysis is a fundamental stoichiometric calculation in all experimental and industrial chemistry: determining theoretical yield, calculating percent yield = (actual/theoretical) × 100, and planning reactions to ensure the desired reagent is the limiting one (for cost, safety, or se…
In industrial processes, the limiting reagent is often chosen to be the more expensive or more hazardous material to avoid waste or accumulation of excess reactive chemical. Understanding which reagent limits the reaction prevents dangerous accumulation of unreacted excess oxidising agents or other …
