How does solute-solvent interaction affect solubility?
How does solute-solvent interaction affect solubility?
Solute-Solvent Interactions Affect Solubility Strong solute-solvent attractions equate to greater solubility while weak solute-solvent attractions equate to lesser solubility. In turn, polar solutes tend to dissolve best in polar solvents while non-polar solutes tend to dissolve best in non-polar solvents.
How do you determine solvent and solute interactions?
Qualitatively, one can determine the solubility of a solute in a solvent by using the rule “like dissolves like”. In general, solutes whose polarity matches that of the solvent will generally be soluble. For example, table salt (NaCl) dissolves easily into water (H2O) because both molecules are polar.
What is a solute-solvent interaction?
Dipole-induced dipole interactions are invoked when a non-polar molecule dissolves in a polar or a dipolar solvent. The assumption is that the solute dissolves because the forces of attraction between the solvent and the solute are stronger than the intermolecular forces holding the non-polar solute molecule together.
What are the 6 solute-solvent combinations?
Solute-Solvent Combinations
| Solute State | Solvent State | Example |
|---|---|---|
| liquid | liquid | alcohol in water |
| gas | liquid | carbon dioxide in water |
| solid | solid | zinc in copper (brass alloy) |
| liquid | solid | mercury in silver and tin (dental amalgam) |
What are the 5 factors affecting solubility?
Factors affecting solubility
- Temperature. Basically, solubility increases with temperature.
- Polarity. In most cases solutes dissolve in solvents that have a similar polarity.
- Pressure. Solid and liquid solutes.
- Molecular size.
- Stirring increases the speed of dissolving.
Is water a solvent?
Water is called the “universal solvent” because it is capable of dissolving more substances than any other liquid. It is water’s chemical composition and physical attributes that make it such an excellent solvent.
Why are solute solvent interactions stronger?
1. This is precisely the trend expected: as the gas molecules become larger, the strength of the solvent–solute interactions due to London dispersion forces increases, approaching the strength of the solvent–solvent interactions. Virtually all common organic liquids, whether polar or not, are miscible.

What are the 3 factors affecting solubility?
If Gases as a solute needs to be dissolved in a solvent, there are factors influencing solubility, such as temperature, nature of solvent and solute, and pressure.
What are the 10 factors affecting solubility?
What are three common solvents?
Common examples of solvents include water, ethanol, methanol and acetone. The term ‘solvent’ can be defined as a substance that has the ability to dissolve a given solute to form a solution with it.
How does the nature of the solute and solvent affect the dissolution?
If the solute binds to other solute (X-X bond) more strongly than the solute binds to the solvent (X-Y bond), then the dissolution is not energetically favorable. The nature of the solute (X) and solvent (Y) determines whether dissolution is energetically favorable or unfavorable.
How are intermolecular forces related to solvation?
Many intermolecular forces can contribute to solvation, including hydrogen bonding, dipole -dipole forces, Van Der Waals forces, and ion -dipole interactions. The strength of the intermolecular forces between solutes and solvents determines the solubility of a given solute in a given solvent.
Why is potential energy lower when solute and solvent are combined?
In this case, the potential energy is lower when the solute and solvent can form bonds. If the X-Y attractions are stronger than the X-X or Y-Y attractions, the dissolution reaction is exothermic and releases energy when the solute and solvent are combined.
How is solvation related to the formation of a solution?
After dissolution occurs, solvation follows. If solvation releases more energy than is consumed during dissolute, then solution formation is favored and the solute is soluble in the solvent. Many intermolecular forces can contribute to solvation, including hydrogen bonding, dipole-dipole forces, and Van Der Waals forces.
