The partial weight of some material component in a mixture of materials or in a compound per unit weight of the mixture or the compound. For example, the gravimetric density of hydrogen in TiH2 is 0.04 (grams of hydrogen)/(gram TiH2), or in other words the hydrogen weight percentage in TiH2 is 4%.
The method of determination of mass as precipitates, from ionic solution after filtration ,washing and weighing the product is termed as

gravimetric method is determination of weight of elements in the solution by precipitation.
Gravimetry is a part of physics which deals with the calculations about the strengths of gravitational fields.
The gravimetric factor is related to the percentage of element (or ion) to be determined in the precipitate (as compound).
gravimetric analysis is the study of weighing certain compounds, comparing, heating, precipitating, to give us the mass of a specific molecule as a result gravimetric analysis is the study of weighing certain compounds, comparing, heating, precipitating, to give us the mass of a specific molecule as a result
Whatman filter paper no. 40 is recommended for gravimetric quantitative analysis. Some characteristics are: - flow rate: medium - Herzberg filtration speed: approx. 340 - porosity: approx. 8 micrometers - ash: max. 0,oo7 % - thickness: 210 micrometers - weight: 95 g/m2
Many methods exist: - distillation - crystallization - sieving - electromagnetic separation - decanting - gravimetric - radiometric - centrifuging - solvent extraction - ion exchanging -etc.
An insoluble compound was precipitated. This is an important procedure in gravimetric analysis, chemical engineering, foods technology, water treatment, separation of components etc.

The gravimetric factor is related to the percentage of element (or ion) to be determined in the precipitate (as compound).
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.

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.
gravimetric analysis is a type of analysis that involves precipitation and weighing
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.
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.
