How to Analysis Sulphate in Water

Determination of Sulphate Sulphate ions in water present usually in the form of compounds like CaSO4,MgSO4,Na2SO4 etc.  The determination of sulphate ions is water in based on the fact that when water is treated in cold with benzidine hydrochloride solution, the sulphate ions get precipitated as insoluble benzidine sulphate C12H8(NH2)2.2HCl + Na2SO4   ——-> C12H8(NH2)2.H2SO4 + 2NaCl [...] Related Topics:ALKALINITY WATER ANALYSIS Alkalinity in Water Alkalinity means the find the am

Determination of Temporary Hardness

Estimation of  Water Hardness The estimation of water hardness as applied to boiler water and other water is great interest for the chemical industry in general.the determination of water hardness has always been an especially important factor in the manufacturing control of sugar industry, pharmaceuticals, food processing, leather, gums, adhesives, textiles etc. Determination of Hardness  [...] Related Topics:WATER HARDNESS Temporary and Permanent Hardness For convenience, hard water is class

Chlorides in Water

Chloride Analysis  Chloride the chloride ions remain presents in the water in the form of one or more of the compounds like CaCl2, MgCl2,NaCl and etc. The estimation of chloride ions is generally, made by titrating the water sample against a standard solution of silver nitrate using potassium chromate as indicator. The added AgN03 precipitates chloride [...] Related Topics:ALKALINITY WATER ANALYSIS Alkalinity in Water Alkalinity means the find the amount of...ESTIMATION OF WATER HARDNESS Water
