Whether you use the term molarity, concentration or solubility they all represent the maximum amount of solute that can successfully be dissolved in a solvent. 

Understanding the Solubility Rules

Concept #1: The Rules for the Solubility of a compound

Certain positive ions combine with negative ions to form either a liquid, aqueous, solid or gaseous compound. The Solubility Rules help us determine which form is created. 

Concept #2: The meaning of the terms soluble and aqueous

Saying a compound is soluble means that the compound will dissolve into aqueous ions in a solvent. These ions can conduct electricity and are called electrolytes

Concept #3: The meaning of the terms insoluble and precipitate

Saying a compound is insoluble means that the compound will not dissolve into aqueous ions and forms a solid called a precipitate, which will not conduct electricity.
