ADVERTISEMENTS: In this article we will discuss about the gravimetric method for estimation of sulphate in plants. Principle: Sulphate is precipitated as barium sulphate in hydrochloric acid medium by the addition of barium chloride solution. The reaction is carried out near the boiling temperature. The precipitate is filtered and washed to remove the chlorides, then [.] Nevertheless, a gravimetric method could work with any reaction producing precipitate. In the nineteenth century and earlier, many precipitations gravimetric methods were developed, often to analyze ore. A total analysis method typically provides better than 0.1% accuracy, which means that the analyte is represented by 99.99% of the precipitate.What is Gravimetric Analysis? Gravimetric analysis is a method in analytical chemistry to determine the quantity of an analyte based on the mass of a solid. Example: Measuring the solids suspended in the water sample – Once a known volume of water is filtered, the collected solids are weighed. The principle of Gravimetric Analysis:

2. Suppose that a small portion of the sulfate precipitated as sodium sulfate rather than as barium sulfate. How would this affect the result of the analysis? 3. From the following list, identify the interfering species for the sulfate determination method used in this experiment: Mg2+, Pb2+, Na+, NO3-, Cl-, PO43-.
Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as .The sample containing sulfate is then reacted with an alcohol solution of barium chloride and methylthymol blue (MTB) at a pH of 2.5-3.0 to form barium sulfate. The combined solution is raised to a pH of 12.5-13.0 so that excess barium reacts with MTB. The uncomplexed MTB color is gray; if it is all chelated with barium, the color is blue.Gravimetric methods: The . quantitative methods. that are based on determining the . mass. of a . pure compound . to which the . analyte. is . chemically related. • Precipitation gravimetry: The . analyte. is separated from a solution of the sample as a . precipitate. and is converted to a compound of known composition that can be weighed .4.2 Determination of sulphate as barium sulphate: Sulphate ions are precipitated from the solution as Barium sulphate with the addition of adding barium chloride Barium sulphate has solubility about 3 mg L-1 at the ordinary temperature in water. The solubility of barium sulphate increases in presence of mineral acids due to formation of .

Gravimetric analysis is a quantitative evaluation of laboratory techniques based primarily on the size of an analyte’s mass. Gravimetric analysis can be used in real life for many users, such as monitoring lead levels in water for human consumption, which, if not monitored, could lead to poisoning and death.1.2 This method is suitable for all concentration ranges of sulfate (SO 4-2); however, in order to obtain reliable readings, use a sample aliquot containing not more than 40 mg/L of SO 4-2. 1.3 The minimum detectable limit is approximately 1 mg/L of SO 4-2. 2.0 SUMMARY OF METHOD 2.1 Sulfate ion is converted to a barium sulfate suspension under The Gravimetric Estimation of Barium: The given barium chloride solution exists made up of a definite volume. A measured volume of it exists then treated with dilute sulphuric acid and barium precipitated as barium sulphate. The precipitated barium sulphate exists split and weighed. The mass of Barium in the total of the given solution exists .
