Solubility and Solubility Curves

When preparing a solution, that is, when dissolving a solute in a given solvent, the molecules or ions of the solute separate, remaining dispersed in the solvent.
We can establish a relationship between different solutes and the characteristics of their aqueous solutions through very simple experiments carried out at the same temperature. Note the following situations:
THE)


B)

As we look at the solutions THE and B, we noticed that salt is less soluble than sugar and, based on this fact, we can generalize:
Saturated solution: is the one that contains the maximum amount of solute in a given amount of solvent, at a given temperature; the relationship between the maximum amount of solute and the amount of solvent is called the solubility coefficient. Example: The maximum amount of salt (NaCl), which dissolves in 100 g of H2At 20°C, it is 36 g; the solution is called saturated.
A solution with an amount of solute less than the solubility coefficient is called a solution. unsaturated or unsaturated.
