Other conditions being the same, solids vary greatly in their solubility in liquids. The London dispersion forces, dipoledipole interactions, and hydrogen bonds that hold molecules to other molecules are generally weak. As the molecular mass of the alcohol increases, so does the proportion of hydrocarbon in the molecule. solutions and solubility assignment quizletwhat are leos attracted to physically. The resulting lemonade is a homogeneous solution because, once stirred in, the substances are uniformly combined and should not separate when the lemonade is left standing. When a solute dissolves, its individual atoms, molecules, or ions interact with the solvent, become solvated, and are able to diffuse independently throughout the solution (Figure \(\PageIndex{1a}\)). Air, for example, is a solution. Water is very polar You may print and distribute up to 200 copies of this document annually, at no charge, for personal and classroom educational use. Surface waters often contain visible particles that make it look cloudy.

Factors that affect solubility include: The concentration of the solute The temperature of the system For example, organic liquids such as benzene, hexane, \(CCl_4\), and \(CS_2\) (S=C=S) are nonpolar and have no ability to act as hydrogen bond donors or acceptors with hydrogen-bonding solvents such as \(H_2O\), \(HF\), and \(NH_3\); hence they are immiscible in these solvents. The solubility has been dependent on the bonding of solute molecules with the solvent. Because all these solvents consist of molecules that have relatively large dipole moments, they can interact favorably with the dissolved ions. Chemical formula When a solution is saturated and excess solute is present, the rate of dissolution is exactly equal to the rate of crystallization (Figure \(\PageIndex{1b}\)). It is not surprising, then, that nonpolar gases are most soluble in nonpolar solvents. Questions and Answers ( 2,600 ) 2 compounds:.
