Solution
Check
1. Calculate the moisture content for each sample using the formula:
Moisture content of soil (W) =
W2 - W3
/
W3 - W1
* 100 %
Residual Chlorine (mg/l) =
V1 * Normality of sodium thiosulphate solution * 3545
/
Volume of sample (ml) V2
Where,
V1 = ml titration for sample
V2 = ml titration for blank
N = Normality of sodium thiosulphate solution (0.025N)
Residual Chlorine (mg/l) =
0.15 * 0.025 * 3545
/
100
=
0.132 mg/L
Permissible limit of residual chlorine is 0.2 mg/L .
