imiting Reagents: 1. Explain the relationship between limiting reagent problems and titrations problems Below is a titration curve of a sample of strong acid being titration with strong base. On the curve identify what the limiting reagent is in the following areas: (1) before the equivalence point, (2) at the equivalence point, and (3) after the equivalence point 14 12 10 Equivalence i point pH 10 20 2530 40 50 Volume NaOH added itration curve of strong acid Cl) with a strong base (NaOH) . Explain why, at each point on the titration curve, knowing the limiting and excess reagents is Take the reaction: NH, + 02 â NO + H2O. In an experiment, 3.25 g of NH, are allowed to react with 3.50 g of O2 a. Which reactant is the limiting reagent? b. How many grams of NO are formed? c. How much of the excess reactant remains after the reaction? If 4.95 g of ethylene (C2H) are combusted with 3.25 g of oxygen. a. What is the limiting reagent? b. How many grams of Co2 are formed?
