Acidimetry refers to the process of determining the acidic properties of a substance. There are various synonyms that can be used to describe this process such as acid analysis, acidometry and titration. Acid analysis is the quantitative determination of the acid present in a sample. On the other hand, acidometry is a process of determining the quantity of acid in a solution using a standardized solution of a known concentration. Titration, also known as volumetric analysis, is a chemical technique used to determine the concentration of one reactant in a known mixture. Overall, these synonyms can be used interchangeably to refer to the process of measuring the acidic properties of a substance.
