When a solute dissolves in a solvent, what happens?

In summary, when a solute dissolves in a solvent, the intermolecular forces between the solute and solvent molecules are overcome, creating space for the solute molecules in the solvent. This does not result in a chemical bond, but rather physical intermolecular forces.

Hi. When a solute dissolves in a solvent, what is actually happening? for example, when sugar dissolves in water, the process I've been given in my book is:

-The intermolecular forces between the sugar molecules is overcome

-The intermolecular forces between some of the water molecules must be overcome, to make space for the sugar molecules

-intermolecular forces form between the sugar and water molecules.

Does that mean that sugar and water molecules chemically bond?

If possible, could someone please explain this in greater detail.

Thanks,
Dan

No there is no chemical bond as such, only physical inter molecular forces.

oh ok. Thanks
 

What is a solute and a solvent?

A solute is a substance that is being dissolved in a solvent. A solvent is a substance that has the ability to dissolve other substances.

What happens when a solute dissolves in a solvent?

When a solute dissolves in a solvent, the individual particles of the solute separate and become surrounded by the particles of the solvent. This process is known as solvation.

What are the factors that affect solubility?

The factors that affect solubility include temperature, pressure, and the chemical properties of the solute and solvent. Generally, increasing temperature and pressure can increase solubility, while the chemical properties of the substances can also affect their ability to dissolve in each other.

What is the difference between a saturated and unsaturated solution?

A saturated solution is one in which no more solute can be dissolved in the solvent at a given temperature and pressure. An unsaturated solution is one in which more solute can still be dissolved in the solvent.

How does the concentration of a solution change when a solute dissolves in a solvent?

The concentration of a solution increases when a solute dissolves in a solvent, as the volume of the solution remains the same while more solute particles are added. This results in a higher ratio of solute particles to solvent particles, leading to a higher concentration.
