Solubility

• The solubility of a compound describes how easily it dissolves in a particular solid, liquid or gas called a "solvent." In the laboratory, the most common solvents are liquids because they are the easiest to handle.
  
  The extent of a compound's solubility in a particular solvent depends on the interactions between the compound, called the "solute," and the solvent. If there are few interactions between the solute and the solvent, then the compound will have a low solubility in the solvent. But if there are many interactions between the solute and solvent then the solubility will be high.
