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%.

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).
What is digestion in gravimetric analysis?
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
Why Whatman filter paper no 40 is used in gravimetric experiments?
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
What can a mixture be separated by?
Many methods exist: - distillation - crystallization - sieving - electromagnetic separation - decanting - gravimetric - radiometric - centrifuging - solvent extraction - ion exchanging -etc.
What is the significance of precipitation in laboratory procedure?
An insoluble compound was precipitated. This is an important procedure in gravimetric analysis, chemical engineering, foods technology, water treatment, separation of components etc.
What is the method of geophysical explotion in the case of disposit of minerals found on Earth's crust using the difference in density of substance?
Look up 'Gravimetric Surveys' or 'Microgravimmetry'
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).
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.

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.
What distinguishes gravimetric anlaysis from other forms of analysis?
gravimetric analysis is a type of analysis that involves precipitation and weighing
What is gravimetric finish?
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.
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.
What has the author Laszlo Erdey written?
Laszlo Erdey has written: 'Gravimetric analysis'
What is limiting reactant between KCl and silver nitrate in gravimetric titrations?
silver nitrate
What is precipitation in respect to wet chemical analysis?
Precipitation is an important process in gravimetric analysis.
Why should excess complexing agent be avoided in gravimetric analysis?
To increase solubility product constant by complexation
