    Solubility Process

    solubility process depends on some factors like:

    1- The type of both solvent and solute
    2- The bonds among the atoms of solvent and the atoms of the solute.
    3- The intermolecular forces among the molecules of both solvent and solute.
    4- The stability of the solution

    Secondly, The interpretation through an example :

    Dissolution of table salt in water:

    Water is a polar solvent and table salt is a polar solute. Therefore, sodium chloride dissociates into positive sodium ions and negative chloride atoms.

    Water molecules separate the negative ions of table salt from the positive ions and attraction is occurred between ions of water and ions of table salt.

    So, the stability produced from dissolving is higher than the stability loss from separating salt ions due to the decrease of the potential energy of the solution.

    Here we find that:

    1- The intermolecular forces among the molecules of solvent and solute are greater than those among the molecules of solvent only or those of the solute only.

    2- The formed bonds between solvent (water) and solute (sodium chloride) are greater than the broken bonds.
