History. Ellagic acid, gallic acid, and pyrogallic acid were first discovered by chemist Henri Braconnot in 20 Julius Löwe was the first person to synthesize ellagic acid by heating gallic acid with arsenic acid or silver oxide.: 20 Maximilian Nierenstein studied natural phenols and tannins found in different plant species.

Working with Arthur George Perkin, he prepared ellagic acid. dye was used for Cr VI determination over 28 days with fresh M sulphuric acid prepared every week. Secondly, % DPC and M sulphuric acid reagent mixture was prepared and used for Cr VI.

A selective colorimetric-solid-phase extraction (C-SPE) method for the determination of total vanadium in water samples was developed. This method introduced a new variation of C-SPE. It is used in the determination of phosphoric acid, chiefly for the purpose of preventing the precipitation of phosphates of iron and alumina by ammonia, and in a few similar cases.

The commercial crystals are used; they should be free from sulphuric acid and leave no ash on ignition. Hydrochloric Acid, HCl in water, (sp. It contains. Based on recommendations from the scientific editors of ACS Journals.
