In this type of problem we don't use "s"s. The molar solubility is known, so we find the 2 0 obj Mechanism Of Solubilization 5. Poor water solubility is the major drawback for the various types of drugs and many approaches have been introduced for the solubility enhancement of such drugs. �{8o�K�Tm��61R� Types of Solid Solutions The name – substitutional-of this solid solution tells you exactly what happens as atoms of the parent metal are replaced or substituted by atoms of the alloying metal. x��\Yo�6~7���� ZA�)RG�3��IƃE��C�n���v�vf'�~���HI�ԙ`0�T,�:Y�}��~s���g�}w�d�_]~\_e�'g���N�>߭O~\}�ٮ�7����gO�?˞��������� <>>> Salts of ammonium (NH 4 +) and Group IA are always soluble.

Many factors such as type of solute, type of solvent and temperature affect the solubility of a solute in a solution. For many compounds, the solubility increases with temperature. <> See Page 1. 2. a. SOLUBILITY RULES 1.

There are three different types of solubility; soluble, slightly soluble, and insoluble. 1 0 obj The saturated solution is heated to 100 o C. All the solutes are dissolved in water.

Application of Solubility 7. is an important factor, with a higher solubility correlating with an increased absorption [2,6]. Solubility is defined as the equilibrium amount of a crystalline compound that can be dissolved in a specific solvent system at the given process conditions, of which the temperature is often the most influential parameter. ;��Ε�B��'KzE���'��x��Kt�- }Ep�/�= D�d��8h���L`\$ �1W��\$���^hj�� # Z�G���\��Th W���܃P�� <>>> Marine life depends on the specific E.g.
