Although the terms reactant and reagent are often used interchangeably, a reactant is more specifically a substance that is consumed in the course of a chemical reaction. Solvents, although they are involved in the reaction, are usually not referred to as reactants.hen purchasing or preparing chemicals, reagent-grade describes chemical substances of sufficient purity for use in chemical analysis, chemical reactions or physical testing. Purity standards for reagents are set by organizations such as ASTM International or the American Chemical Society.
A limiting reagent is a chemical reactant that limits the amount of product that is formed. The limiting reagent gives the smallest yield of product calculated from the reagents (reactants) available. This smallest yield of product is called the theoretical yield. To find the limiting reagent and theoretical yield, carry out the following procedure: 1. Find the moles of each reactant present. 2. Calculate the moles of a product formed from each mole of reactant. 3. Identify the reactant giving the smaller number of moles of product. This reactant is the Limiting Reagent: 4. Calculate the grams of product produced by the Limiting Reagent. This is the theoretical yield. THEORETICAL YIELD The theoretical yield is the amount of the product in g formed from the limiting reagent. theoretically possible (same as Step 4 above). The actual yield is the amount of the product in g actually formed in the laboratory. The percent yield is the percent of the product formed based upon the theoretical yield.
