what is gravimetric analysis chemistry

Thermogravimetric analysis, also known as TGA is a technique frequently used in thermal analysis in which a change in the weight of a substance is recorded as a function of temperature or time. Composition, purity, decomposition processes, decomposition temperatures, and absorbed moisture content are among the characteristics and behavior that can be .Gravimetric analysis and volumetric analysis are two important methods in quantitative chemical analysis. While gravimetric analysis relies on the measurement of mass and the formation of a precipitate, volumetric analysis involves the measurement of volume and the reaction between the analyte and a standardized solution. Method 925.10 in Official Methods of Analysis, 18th Edition (AOAC International, 2007) provides an approved method for determining the moisture content of flour. A preweighed sample is heated for one hour in a 130 o C oven and transferred to a desiccator while it cools to room temperature.

In most cases the precipitate is the product of a simple metathesis reaction between the analyte and the precipitant; however, any reaction that generates a precipitate potentially can serve as a gravimetric method. Most precipitation gravimetric methods were developed in the nineteenth century, or earlier, often for the analysis of ores . Because the release of a volatile species is an essential part of these methods, we classify them collectively as volatilization gravimetric methods of analysis. 7.4: Particulate Gravimetry Precipitation and volatilization gravimetric methods require that the analyte, or some other species in the sample, participate in a chemical reaction.

Gravimetric analysis is a technique through which the amount of an analyte (the ion being analyzed) can be determined through the measurement of mass. Gravimetric analyses depend on comparing the masses of two compounds containing the analyte. The principle behind gravimetric analysis is that the mass of an ion in a pure compound can be . 4. Types of Gravimetric Analyses: • There are two main types of gravimetric analyses: A) Precipitation – analyte must first be converted to a solid (precipitate) by precipitation with an appropriate reagent. The precipitates from solution is filtered, washed, purified (if necessary) and weighed. B) Volatilization – In this method the analyte or its decomposition .

analysis is performed, it is almost impossible to prevent photodecomposition of the wet silver chloride precipitate. Generally, the effect is small and can be ignored provided that exposure to direct sunlight, or extended exposure to fluorescent lights, is avoided. The simplest way to minimize photodecomposition is to store the The gravimetric analysis technique measures a change in mass to determine the concentration of a substance or the mass of a substance. Analyses are also known as analyses because they involve chemical substances.
