Some of the water quality parameters are measured by titrating a water sample with a titrant. Group-I gives a list of parameters and Group-II gives the list of titrant.

Groups - I Groups - II

P. Alkalinity 1. $N / 35.5 A g N O_{3}$

Q. Hardness 2. $N / 40 N a_{2} S_{2} O_{3}$ .

R. Chloride 3 $H_{2} S O_{4}$

S. Dissolved oxygen 4. $N / 50 E D T A$

Codes:

P - 1, Q - 2, R - 3, S - 4
