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
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 co precipitation?
this method is used for making the compound in gel form
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 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 is precipitation in respect to wet chemical analysis?
Precipitation is an important process in gravimetric analysis.
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 distinguishes gravimetric anlaysis from other forms of analysis?
gravimetric analysis is a type of analysis that involves precipitation and weighing
What is digestion in gravimetric analysis?

What are the different steps involved in precipitation method of gravimetric analysis?
various method or steps involved in gravimeteic analysis are as followsprecipitationfiltrationwashingdrying or ignitionweighing
What are the common error in a gravimetric analysis lab?
Adding too much of the ion that causes the precipitate to form. This is because a large excess can cause co-precipitation which adds excess and unneeded mass.
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.
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 has the author Laszlo Erdey written?
Laszlo Erdey has written: 'Gravimetric analysis'
What is the difference between volumetric analysis and gravimetric analysis?
AnswerVolumetric analysis or titration is a common laboratory method of chemical analysis which can be used to determine the concentration of a known reactant; volumetry is a quantitative method of analysis.Qualitative analysis is used to separate and detect elements, functional groups, molecules etc. in a sample substance, without specifying concentration.
What are the requirements for a successful gravimetric analysis?
The steps commonly followed in gravimetric analysis are (1) preparation of a solution containing a known weight of the sample, (2) separation of the desired constituent, (3) weighing the isolated constituent, and (4) computation of the amount of the particular constituent in the sample from the observed weight of the isolated substance.
Why should excess complexing agent be avoided in gravimetric analysis?
To increase solubility product constant by complexation
