Explain with an example equilibrium involving dissolution of solids in liquids. |
|
Answer» Solution :Example : `CO_(2(g))hArrCO_(2)("solurion")` When a bottle of soda water is OPENED, some of the dissolved `CO_(2)` in it, bubbles out in the form of froth. In the solution, there is a dynamic equilibrium between `CO_(2)` MOLECULES in the gaseous state and the `CO_(2)` molecules dissolved in the liquid under pressure. At equilibrium, the mass of the dissolved gas in a given mass of water is PROPORTIONAL to the pressure above the solution. This is in ACCORDANCE with the HENRY's law of gas solublity in a liquid. |
