We can see that points A, B, C and D are all still coplanar points. Point E is not coplanar with the original four points. But if I pick any group of three of the points, even a group containing point E, those three points will be coplanar. The reason is the statement given above - any three points in 3-dimensional space determine a plane.
Definition of solubility. 1  1 : the quality or state of being soluble. 2  2 : the amount of a substance that will dissolve in a given amount of another substance.
Concept: Solubility is the ability of a compound to be dissolved in a solvent. The solubility of organic compounds are very important in organic reaction and purification. Theory: The solubility of organic compounds is a function of the polarities of both the solvent and the solute (dissolved material).A general rule is  Like dissolves like.. This means if the solute is very polar, a very polar solvent is needed to dissolve it; if it is nonpolar, a nonpolar solvent is needed.he solubility of organic compounds is a function of the polarities of both the solvent and the solute (dissolved material).
