Definition of Gravimetric Analysis

Definition
Gravimetric analysis (GA) is a part of quantitative analysis and is defines as the process of weighing an element or a definite compound of the element in as pure form as possible.
 
The determination of GA is depends on transformation of the element into a pure stable compound which can be readily converted into a form suitable for weighing. The weight of the element is calculated by knowledge of the formula of a compound and the relative atomic masses of the constituent elements.
 
Advantages:
·  Precise and accurate
·  Errors are readily checked
·  Absolute method
·  Inexpensive apparatus
 
Disadvantages:
·  Time consuming
·  Slow method
·  Tedious
 
Application of Gravimetric Analysis
·  Analyze standard that are used for testing or calibration of instruments.
·  Analyze the compound with high accuracy
·  Applicable only for those substances which form metallic compounds on ignition and which do not contain volatile matter.
