WebEXAMPLE 3.1.2 Application of Henry’s Law At 20 °C, the concentration of dissolved oxygen in water exposed to gaseous oxygen at a partial pressure of 101.3 kPa is 1.38 \(××\) 10−3 mol L−1. Use Henry’s law to determine the solubility of oxygen when its partial pressure is 20.7 kPa, the approximate pressure of oxygen in earth’s atmosphere. WebWhenever an osmotic pressure is built-up, according to Pascal law it will act equally on all of the solution boundaries. It will then push any boundary that is free to move. The osmotic pressure acts on a moving boundary from inside the solution, and in order to keep the system under balance a similar extra external pressure should act on it from outside.
