Document Summary
Chem 101: solubility rules and identification of reaction occurrence. In general, many 1+ and 1- ion compounds are soluble in water, in other words they exist in aqueous states when dissolved in water. 2- ion compounds and 2+ with 1- ion compounds are also soluble in water solvent and are in an aqueous state. Many 2+ with 2- ion compounds will not be soluble in water and therefore exist in a solid state when in water. 2+ with 3- also follows that same rule of being insoluble. 3+and 3- ion compounds (for the majority of this course) will always be insoluble. There are some notable exceptions to this in organic chemistry, but those exceptions are to be discussed in a different higher division course, so for chem 101 purposes just know that 3+ with 3- will always be insoluble. 3+ and 2- ion compounds also tend to be insoluble.
