Moreover, I could analyze Turbidity, Free Chlorine, SO4(2-), PO4(2-), TDS, TSS.For example, To identify the chloride
ions by using Argento metric method&Mohr’s Method by the addition of AgNO3 followed by K2CrO4was the indicator
resulting the colour changes was observed.(yellow to brick red), which was the end point to measure the chloride ion
presented in the whole of the effluent water. Initially, a silver-chromate(Ag2CrO4) ppt will be formed as a red color,
then changed in to brownish grey(AgOH)(PH will be 7-10&>10 by Mohr’s).
2AgNo3 +K2CrO4-------------->Ag2CrO4+2KNO3(Red) PH <7
AgNO3+-Cl----------------------->AgCl (white ppt) PH >10
