EXPERIMENT :Estimation of Free Chlorine

I want Result & Analysis for this experiment includes Precautions

 

 

Calculations: Normality of water sample: N¡Vi(water sample) = N2V2(NazS2O3) N15NV2(NazS203)/V1 N= x3.7 40 1.85 x 10-3 50 Amount of free chlorine in water sample: Amount of free chlorine in water sample= N1 x equivalent weight of chlorine = N1 x 35.5 g/L = N1 x 35.5 x 103 ppm = 1.85 x 10-3 × 35.5 x 103 ppm Amount of free chlorine in water sample = 65.675 ppm
