Henry’s Law and Its Application – Solution and Colligative Properties – Chemistry Class 12


Do subscribe to Ekeeda Channel and press bell icon to get updates about latest engineering HSC and IIT JEE main and advanced videos in the last lecture we have studied that the effect of pressure is plays a very important role in solubility of gas this effect of pressure is nothing but Henry’s law let us study it in deep so what Henry’s law says Henry knows is that if the pressure is more which is applied on the solution then the solubility also increases let us say I’ll say policing continuation of Henry’s law and its application so let us see what is henry’s law Henry’s law says that the solubility of the gas in liquid at a constant temperature is slightly proportional to the pressure of the gas above the solution it means if you apply both pressure then the solute E of gas will be more and if you apply less pressure then the solubility of the gases in the liquid will be less so it is given in the formula s is slightly proportion to P so therefore solubility is equals to K into P and what is scale case Henry’s constant and s is nothing but solubility of the gas in liquid while P is the pressure that is applied on the gas to get dissolved in the liquid let us see what is Henry’s constant and this constant which is denoted by the letter K is known as it is nothing but the solubility of gas in moles per diem cube at 1 atmospheric pressure at constant temperature so suppose if s is goes to K into P so then will be the Henry’s constant is goes to one atmosphere when the solubility will be 1 or when the pressure will be 1 so now let’s see what are the applications of Henry’s law so these are the applications the first one is production of carbonated beverages as you know many of the calculated beverages like you might be consuming cokes and all they have carbon dioxide or carbonated water in it and what are those they have carbon dioxide gases that are dissolved in the liquid and hence they have a effervescence and hence they have effervescence whenever you have opened the bottle so by dissolving the gases you can make beverages and hence these are the applications of Henry’s law the second one the second one is nothing but the people living at high altitude people living at high altitude there is very small quantity of oxygen present in their environment why because at high altitude the pressure is also very less and hence as we know according to the Henry’s law if the pressure is more the gas that could dissolve in the liquid alone should be more and at high altitude since the pressure is very much less the oxygen in the environment is also very less and hence people face various problems and that problem is known as a knob here which means filling Nassif Nassif lesion of blood in the body will also be less as he bogi which is present in the body it absorbs oxygen but at higher to do the option quantity is less so therefore the people living there faces this kind of problems so thank you friends for watching this video I hope you have liked this video and please don’t forget to subscribe on e Kirra channel and do let your friends also share this video thank you so much
