O TOLIDINE REAGENT FOR CHLORINE ESTIMATION
O-Toluidine Reagent is used for estimation of chlorine from water. 1) Add 1ml of O-Toluidine reagent to100ml of the sample and mix thoroughly. 2)
Allow the sample to stay in dark for 5-15minutes for the colour to develop if the sample is free of chloramine and nitrite and iron are each less than
