Industrial effluents

Inorganic fertilizers

Organic farming

Seawater intrusion in coastal areas

Septic tank effluents

Level 02

Chlorides are leached from various rocks into soil and water by weathering. The chloride ion is highly mobile and is transported to closed basins or oceans.

?Select the various analytical methods that can be used to determine concentration of chloride ions in water.

Level 03

option-1
option-2
option-3
option-4
Level 04

The chloride ions have effect on corrosion. In metal pipes carrying water, chloride increases the electrical conductivity and thus __________ its corrosivity.

Increases

Decreases

Has no effect on corrosion

Level 05

As the chloride ions increase the electrical conductivity of water and thus increases its corrosivity.
