Concept explainers

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".

The steps for determining the concentration of a sample of hydrochloric acid are listed below :Step (1): A 0.1038 M standard sodium carbonate solution was prepared by dissolving 2.750 g ofanhydrous sodium carbonate solid in deionised water and made up to 250.0 cm3.Step (2): 25.0 cm' of the standard solution obtained in Step (1) was transferred to a clean conical flask andthen a few drops of methyl orange were added.Step (3): The sample of hydrochloric acid was put into a burette. The standard solution in the conicalflask was titrated with the hydrochloric acid.Step (2) and Step (3) were repeated for several times.
