What is Gravimetric Analysis

Gravimetric analysis is an analytical technique based on the measurements of mass of solid substances and/or volume of gaseous species. Gravimetric analysis is divided into three parts.

Types of Gravimetric Analysis

i) Mass-Mass relationship

ii) Mass-volume relationship

iii) Volume-volume relationship

Mass-Mass Relationship in Gravimetric Analysis 

It relates the mass of a species (reactant or product) with the mass of another species (reactants or product)

Mass-Volume Relationship in Gravimetric Analysis

It relates the mass of a species (reactant or product) and the volume of a gaseous species (reactant or product) involved in a chemical reaction. Suppose we are provided with ‘a’ gms of NaHCO3 in a vessel of capacity V L and the vessel is heated, so that NaHCO3 decomposes as

Volume-Volume Relationship in Gravimetric Analysis

It relates the volume of gaseous species (reactants or products) with the volume of another gaseous species (reactant or product) involved in a chemical reaction.
