How is air dissolved in water different from ordinary air?

How is heavy water prepared from ordinary water ? Discuss its important physical and chemical properties.

Give reasons for the following: The percentage of oxygen, in air dissolved in water, is higher than the percentage of oxygen in ordinary air.

Select homogeneous and heterogeneous mixtures from the following: Salt solution, petrol and water, sand and charcoal, alcohol and water, air dissolved in water, air, sea water, fruit juices, mist, brass.

Explain why : Air dissolved in water contains a higher proportion of oxygen.

How does oxygen get dissolved in water and how is water deoxygenated ?

Salt and air dissolved in water ………….add taste to water.

Let gas (A) present in air is dissolved in 20 moles of water at 298K and 20 atm pressure. The mole fraction of gas (A) in air is 0.2 and the Henry's law constant for solubility of gas (A) in water at 298K is 1×10^5atm.The number of mole of gas (A) dissolved in water will be

Henry's law constant for the solubility of nitrogen gas in water at 298 K is 1.0 xx 10^(-5) atm . The mole fraction of nitrogen in air is 0.8 .The number of moles of nitrogen from air dissolved in 10 mol of water at 298 K and 5 atm pressure is

The Henry's law constant for the solubility of N_(2) gas in water at 298K is 1.0 xx 10^(5) atm. The mole fraction of N_(2) in air is 0.8 . The number of moles of N_(2) from air dissolved in 10 moles of water at 298K and 5 atm pressure is

Draw a ray diagram showing the path of rays of light when it enters with oblique incidence (i) from air into water , (ii) from water into air.
