Write any 2 characteristics for ideal and nonideal solutions?
Answers
Characteristics of Ideal Solutions
They follow Raoult's Law. ...
The enthalpy of mixing of two components should be zero, that is, Δmix H = 0. ...
The volume of the mixing is equal to zero that is, Δmix V = 0. ...
The solute-solute interaction and solvent-solvent interaction is almost similar to the solute-solvent interaction.
Explanation:
Table: Ideal and non-ideal solutions
Ideal solutions Non-ideal solutions
2. neither heat is evolved nor absorbed during dissolution. 2. Endothermic dissolution; heat is absorbed.
3. total volume of solution is equal to sum of volumes of the components. 3. Volume is increased after dissolutionToo often, you would hear your parents telling you to be an ‘ideal’ kid. What do they mean by that? You better know that! But, when we say ideal and non-ideal solutions, what do we mean? In this chapter, we will study all about ideal and non-ideal solutions. We will look at their properties and examplesIn 1986, it was a French Chemist, Francois Marte Raoult who proposed a relationship between partial pressure and mole fraction of volatile liquids. According to the law, ‘the mole fraction of the solute component is directly proportional to its partial pressure’.The solutions which obey Raoult’s Law at every range of concentration and at all temperatures are Ideal Solutions. We can obtain ideal solutions by mixing two ideal components that are, solute and a solvent having similar molecular size and structure.
For Example, consider two liquids A and B, and mix them. The formed solution will experience several intermolecular forces of attractions inside it, which will be:A – A intermolecular forces of attraction
B – B intermolecular forces of attraction
A – B intermolecular forces of attraction
The solution is said to be an ideal solution, only when the intermolecular forces of attraction between A – A, B – B and A – B are nearly equal.
