WebIn this colorimetric method, use for drinking water, wastewater and seawater, nitrate is reduced to nitrite with hydrazine sulfate. The diazonium reagents then react with the nitrite to produce a red color. The intensity of the color is proportional to the original amount of nitrate and nitrite present in the sample. WebFeb 22, 2024 · Hardness is classified into two types: 1. Temporary Hardness. The presence of bicarbonate and carbonate ions of calcium and magnesium in the water causes temporary hardness. i.e. Ca (HCO3) 2, Mg (HCO3) 2, Fe (HCO3) 2. Therefore, this hardness is known as Carbonate Hardness. This hardness can be easily removed …
WebThe hardness of well water in Enugu metropolis (Asata, Coal Camp and New Haven) was determined using complexometric titration with EDTA (Ethylene Diaminetetracetic Acid) which is the most widely used complexing agent for the analysis of water hardness. During titration, indicator such as Erichrome Black-T was used which acts a triprotic acid.
