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 in gravimetric analysis?
It is the precipitation of the impurities(the un wanted ppt) with the wanted precipitation and it has four types occlusion(absorption),adsorption,post-precipitation,formation of mixed crystals
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
How do you test for fiber in food?
Fiber can be tested in food by weighing or chemical analysis. Weighing (or the gravimetric method) involves digesting components of the food using enzymes. After all the digestible material is removed from the food, the remaining fiber is weighed. Chemical analysis involves determining the amounts of individual monomers in the fiber to quantify how much fiber is in the food.
What distinguishes gravimetric anlaysis from other forms of analysis?
gravimetric analysis is a type of analysis that involves precipitation and weighing
What is precipitation in respect to wet chemical analysis?
Precipitation is an important process in gravimetric analysis.
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.
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 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 different steps involved in precipitation method of gravimetric analysis?
various method or steps involved in gravimeteic analysis are as followsprecipitationfiltrationwashingdrying or ignitionweighing
Why should excess complexing agent be avoided in gravimetric analysis?
To increase solubility product constant by complexation
How can you improve the yield of barium sulphate in a gravimetric analysis?
make barium sulphate to undergo super saturation...
What has the author M D Hawkins written?
M. D. Hawkins has written: 'Calculations in volumetric and gravimetric analysis'
Explain why gravimetric analysis is suitable for the analysis of sulfate ions but not ammonium ions?
The sulphate ions as anion get precipitate easily using suitable precipitants unlike ammonia ions.
Why cncentrated HCl is added in gravimetric analysis?
So that the risk of injuring yourself by HCL is greater hence, making life much more fulfilling.
