Discuss the equilibrium involving dissolution of solids or gases in liquids. |
|
Answer» SOLUTION :Solid in liquids : `square` When you add sugar to water at a particular temperature, it dissolves to from sugar solution. If you continue to which the added sugar REMAINS as solid and the resulting solution is called a saturated solution. Here, as in the previous CASES a dynamic equilibrium is established between the solute molecules in the solid phase and in the solution phase. `{:("Sugar (Solid) ", hArr ," Sugar (Solution)"),("In this process",,),("Rate of DISSOLUTION ",,"Rate of"),(,=,),("of solute",," crystallisation of sulute"):}` Gas in liquids : `square`When a gas dissolves in a liquid under a given pressure, there will be an equilibrium between gas molecules in the gaseous state and those dissolved in the liquid. `square` In carbonated beverages the following equilibrium exists. `CO_(2)(g)hArrCO_(2)(s)` `square` Henry's LAW is used to explain such gas - solution equilibrium processes. |
