Quantitative Determination of Sulphate By Gravimetric Analysis

Analytical & Physical Chemistry ( CP4001) Experiment 4: Quantitative Determination of Sulphate by Gravimetric summary Formal Report Class: DFST/FT/2B/21 abstract The objective of this experiment is to determine the amount of sulfate by gravimetric analysis. The amount of sulfate is determined quantitatively as barium sulfate, BaSO4, by gravimetric analysis. For the experiment, a dilute conk away sustain of barium chloride was slowly added to a hot unknown sulfate final result slightly acidified with concentrated HCl. The precipitate is then filtered come to by suction filtration, washed with water and dried in the oven at 150 degree Celsius for ab forbidden half an age of day and cooled in the desiccator, and weighed as barium sulphate and the fate of sulphate was calculated from the load of barium sulphate. The Molarity of sulphate= 0.004269 M and the concentration of sulphate in g/L= 0.4098g/L. The burthen of barium sulphate was calculated to be 0.0249g. on that point were also no hiccups during the experiment. (133 words) Objective To determine the amount of sulphate by gravimetric analysis. Students can also be long-familiar to the ways to wait out Gravimetric Analysis through this experiment.

Theory Gravimetric analysis has become one of the virtually to accurate classes of analytical methods available. Commonly, gravimetric analysis is being carried out by the following steps: (1) preparing a solution containing a known load, (2) isolation of the desired elements, (3) weighing the separated elements and (4) figuring of the amount of co nstituent in the sample from the observed we! ight of the isolated substance. Precipitation and filtration are the most commonly lend oneself methods to isolate the desired substances from a solution. The reagents used in the reactions present form an insoluble compound with the desired constituents but not precipitate of other elements. Firstly, exactly 25mL of precondition sulphate solution was used so that it would be a fair experiment... If you ask to get a full essay, pronounce it on our website: OrderCustomPaper.com
