Solution:

The domestic sewage of a city was tested for total solids, and the following results were obtained:

Weight of sample of sewage = 900 g

Weight of solids after evaporation of liquid = 0.732 g

Weight of dry residue after ignition = 0.386 g

The volatile solids present is

384.5 ppm

395.6 ppm

406.5 ppm

Solution:

Some of the water quality parameters are measured by titrating a water sample with a titrant. Group-1 gives a list of parameter and Group-2 gives the list of titrants.
Group 1
P. Alkalinity
Q. Hardness
R. Chloride
S. Dissolved oxygen
Group 2
1.     N/35.5 AgNO₃
2.     N/40 Na₂S0₃
3.     N/50 H₂SO₄
4.     N/50 EDTA
The correct match of water quality parameters in Group-1 with titrants inGroup-2 is:

(a)

(b)

(c)

(d)
