Determine the Amount of Sulfate by Gravimetric Method
Jun 24, 2017· Determine the Amount of Sulfate by Gravimetric Method. by koyalirie June 24, 2017. This method is valid for 20-100mg/l. Principle: sulfate ion is precipitated and weighed as BaSO 4. The solution is first acidified with HCL to prevent the precipitation of BaCO 3 and Ba(OH) 2 and it also aids the larger precipitate crystals.

Estimation of Sulphate by Gravimetric Method Plants
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 []

Sulfate Wikipedia
The barium derivative is useful in the gravimetric analysis of sulfate: if one adds a solution of most barium salts, for instance barium chloride, to a solution containing sulfate ions, barium sulfate will precipitate out of solution as a whitish powder. This is a common laboratory test to determine if sulfate anions are present.
