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. Many different reactions can be used here. One example is AgNO3(aq) + NaCl(aq) â AgCl(s) + NaNO3(aq) Ag+(aq) + Clâ(aq) â AgCl(s) c. Write the solubility equation for the precipitate formed above. AgCl(s) â Ag+(aq) + Clâ(aq) 2a. Using the solubility table below predict whether the following compounds are soluble or insoluble in water. Solubility Table Ion Solubility Exceptions NO3 - soluble none ClO4
