The concentration of dissolved oxygen (DO) in cold water can go upto:

Speculate the probable causes of the following phenomena: Decrease in the concentration of dissolved oxygen in water and floating of dead fishes.

Speculate the probable causes of the following phenomena: Decrease in the concentration of dissolved oxygen in water and floating of dead fishes.

Ifthe concentration of dissolved oxygen in water is below X ppm, the growth of fish gets inhibited X is :

Ifthe concentration of dissolved oxygen in water is below X ppm, the growth of fish gets inhibited X is :

One litre sample of sea water is found to contain 5.8 xx 10^(-3) g of dissolved oxygen. Calculate the concentration of dissolved oxygen in sea water in ppm if the density of sea water is 1.03 g cm^(-3) .

The process of 'eutrophication' is due to : increase in concentration of insecticide in water, increase in concentration of fluoride ion in water, The reduction in concentration of the dissolved oxygen in water due to phosphate pollution in water, attack of younger leaves of a plant by peroxyacetyl nitrate.

The Henry's Law constant for oxygen dissolved in water is 4.34 xx 10 ^(4)atm ( mol /L) at 25^(@) C . If the partial pressure of oxygen in air is 0.2 atm under ordinary atmospheric condition calculate the concentration (in mol/litre ) of dissolved oxygen in water equilibrium with air at 25^(@) C
