Chemical Solutions

A solution is one type of homogeneous mixture. Solvation occurs when solution components have similar stabilizing interactions. Two substances are miscible if they can solvate each other at any concentration. The physical and chemical properties of all components change upon dissolution. Wolfram|Alpha has extensive solubility knowledge of various compounds in both polar and nonpolar solvents.
