When assaying for metals, a gravimetric finish produces a small bead of the target metal (post fire assay), which is then weighed. This provides a way of confirming the fire assay figure.

What is gravimetric factor?
A gravimetric factor converts grams of a compound into grams of a single element. For example, we'll find the gravimetric factor of Cl in AgCl. Use the atomic mass of Ag(107.868) and the atomic mass of Cl(35.453) and add them together to get 143.3. Then divide 35.453 by 143.3 to get .2474. .2474 is the gravimetric factor of Cl in AgCl.
What distinguishes gravimetric anlaysis from other forms of analysis?
gravimetric analysis is a type of analysis that involves precipitation and weighing
Types of precipitation in gravimetric analysis?
In analytical chemistry, gravimetric analysis is used to determine an analyte, which is based on the mass of a solid. The types of precipitation in gravimetric analysis are pure precipitation.
How can you improve the yield of barium sulphate in a gravimetric analysis?

Why were the solution of BaCl2 and Na2CO3 used?
Barium chloride: gravimetric determination of sulfateSodium carbonate: qualitative determination of some metals
Why do we multiply the mass of precipitate with a gravimetric factor?
The gravimetric factor is related to the percentage of element (or ion) to be determined in the precipitate (as compound).

Why does solubility play a role in a gravimetric analysis?
Solubility always has to be considered as a source of error in gravimetric analysis because what remains in solution, no matter how little, doesn't get measured (although, it can sometimes be determined indirectly). So, gravimetric results are always erroneously low due to this factor.
