Divers get “the bends” when bubbles of N2 gas form in their bloodstream if they rise too rapidly from a deep dive. Calculate the solubility (mol L−1) of N2 in water (this is roughly equal to the solubility in blood serum) at sea level and at a depth of 300 ft below the surface of the ocean. It is given that: the density of seawater is 1.01 gcm−3, the density of mercury is 13.6 gcm−3 and the Henry’s constant of N2 is 86 × 103 atm.

Answer is 6.4 × 10−3molL−1 but idk how they got it

Solutions

Expert Solution

Scuba divers must be very conscious of Caisson's disease, commonly called 'The Bends'. The Bends is a N2 (Nitrogen) solubility problem. Since the air we breathe is 78% nitrogen, nitrogen is dissolved in all of our tissues. The amount of nitrogen dissolved is related to atmospheric pressure.

Now, Lets calculate the solubility of N2 at the given depth using Henry's law-

When Chlorine gas is used to disinfect drinking water, it hydrolyzes with the water to form hypochlorous acid (HOCl, pKa = 7.54), which is a powerful disinfectant. However, when the acid dissociates to its conjugate base, it becomes a less effective disinfectant. The disinfection power of the acid is 88 times better than its conjugate base, OCl-, on a per-mole basis. Calculate the mass of hypochlorous acid you would need to add to 1 liter of water at pH =...
