Gravimetric precipitation is a method used to measure the amount of precipitation that has fallen over a specific period of time. This method involves collecting the precipitation in a container, weighing it, and then calculating the volume of precipitation based on its weight. It is considered a more accurate way to measure precipitation compared to other methods such as using rain gauges.

What the purpose of the ammonium acetate in the gravimetric determination of aluminum as oxinate?
The purpose of the ammonium acetate in the gravimetric determination of aluminium as oxinate is as a buffer. As more ammonium acetate is added, this caused the complex of the aluminium in the solution to precipitate after the yellow supernatant was formed. Excess ammonium acetate is needed to ensure all of the crystals precipitated out completely.
What is the Difference between co precipitation and post precipitation?
• Precipitation is settling down of insoluble particles from a solution. Co-precipitation is a process in which normally soluble compounds are carried out of solution by a precipitate. • In precipitation, normally insoluble compounds are precipitated. But in co-precipitation normally soluble compounds are precipitated. • Co-precipitation incorporates contaminants into the precipitate, whereas precipitation can result in both pure and contaminated precipitates.
Rain or snow is called what?
precipitation
Stratus is to clouds as rain is to what?
precipitation
What part of speech is precipitation?
The word precipitous is an adjective. It means to be steep.
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 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
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 digestion is necessary in gravimetric titration?
Digestion is necessary in gravimetric titration to ensure complete and uniform precipitation of the solution being analyzed, allowing for accurate measurement of the precipitate. Digestion also helps in converting the analyte into a form suitable for precipitation, and aids in the formation of a crystalline precipitate which can be easily filtered and weighed.
What is gravimitre precipitation method?
Gravimetric precipitation method is a technique used to determine the concentration of a substance in a sample by precipitating the substance and then measuring its mass. This method is commonly used in analytical chemistry for quantifying the amount of a specific element or compound in a solution.
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 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 distinguishes gravimetric anlaysis from other forms of analysis?
Gravimetric analysis measures the mass of a substance to determine its quantity, while other forms of analysis may involve measuring other properties such as volume or concentration. Gravimetric analysis typically provides more accurate results because it directly measures the amount of the target substance, and it is often used for determining the purity of a sample or detecting trace amounts of a substance. The main limitation of gravimetric analysis is that it is time-consuming and may require complex procedures compared to other analytical methods.
What are the common error in a gravimetric analysis lab?
Common errors in a gravimetric analysis lab include incomplete precipitation of the analyte, contamination of the sample, loss of analyte during filtration or washing, and improper drying of the precipitate. These errors can result in inaccuracies in the final weight of the analyte and affect the overall precision and accuracy of the analysis.
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).
