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 […]
