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 titrants.
Group I Group II P. Alkalinity 1. N/35.5 AgNO3 Q. Hardness 2. N/40 Na2 S2O3 R. Chloride 3. N/50 H2SO4 S. Dissolved oxygen 4. N/50 EDTA
The correct match of water quality parameters in Group I with titrants in Group II is
-
- P-1, Q-2, R-3, S-4
- P-3, Q-4, R-1, S-2
- P-2, Q-1, R-4, S-3
- P-4, Q-3, R-2, S-1
Correct Option: C
NA
