Main characteristics for the study of the equilibrium in multicomponent systems:
---- Chemistry deals with mixtures that react
---- It is necesary to know general concepts about mixtures
---- Start with non-reactive mixtures, also with binary mixtures
---- The mixtures are more complex than pure sustances in terms of intermolecular interactions
Intermolecular interactions depends on the species, for example if we talk about a pure system "i" the interactions are going to be: i-i. However if we talk about a binary mixture "i" and "j", the interactions in the system are going to be the following: i-i, i-j, j-j
Example:
Ethanol + Water ---------------> Mixture
50 ml 20 ml 67 mL
What happen to the other 3 ml????
Answer: The total mass is maintained but the volume changes because the intermolecular interactions between the ethanol and water.
Main characteristics of the mixture:
----When species is part of a mixture, it losses it's identity
---- Still, it contributes to the properties of the mixture
---- Total solution properties depend on the amount and their interactions
