Solutions & Solubility

Front

What is a solution?

Back

A solution is a homogeneous mixture composed of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution. Examples include salt in saltwater.

Front

What is a solvent?

Back

A solvent is the substance in which the solute is dissolved to form a solution. Water is the most common solvent.

Front

What does solubility mean?

Back

Solubility is the ability of a substance to dissolve in a solvent at a given temperature and pressure.

Front

What factors affect solubility?

Back

Factors affecting solubility include temperature, pressure, and the nature of the solute and solvent.

Front

What is the difference between polar and nonpolar substances?

Back

Polar substances have a significant difference in electronegativity between atoms, leading to partial charges, while nonpolar substances have an even distribution of charge.

Front

What happens to solubility when temperature increases for most solids?

Back

For most solids, solubility increases as temperature increases.

Front

What is the least soluble salt at 0 ºC among K2Cr2O7, KNO3, KClO3, and Ce2(SO4)3?

Back

KClO3 is the least soluble salt at 0 ºC.

Front

What is an example of a nonpolar solute?

Back

Naphthalene is an example of a nonpolar solute.

Front

What occurs when you add more solvent to a saturated solution?

Back

Adding more solvent to a saturated solution can increase the solubility of the solute.
