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.
Solubility is a measure of the extent to which a compound will. dissolve in a given solvent. In most cases, we are interested in the. solubility of a compound in water. b. Write a chemical equation and a net ionic equation for a reaction which forms a. precipitate.
