In this explainer, we will learn how to describe polar and nonpolar solvents. Solubility can be defined as the tendency of one chemical substance to dissolve in a solvent and form a solution. The solute can be a solid, a liquid, or even a gas and the solvent can be made up of almost any type of molecule. Some substances will be soluble in polar ...
In this video, we will learn how to describe polar and nonpolar solvents. We’ll examine how intermolecular forces between molecules affect solubility and determine the meaning behind the phrase “like dissolves like.”
In this lab, you will explore how polarity affects whether substances dissolve in each other. What is the meaning of “like dissolves like”? Why are nonpolar and polar substances immiscible?
13 gru 2023 · Solvents that are very polar will dissolve solutes that are very polar or even ionic. Solvents that are nonpolar will dissolve nonpolar solutes. Thus water, being polar, is a good solvent for ionic compounds and polar solutes like ethanol (C 2 H 5 OH).
Nonpolar molecules are generally insoluble in polar solvents, as the polar solvent molecules cannot effectively interact with the nonpolar molecules. On the other hand, polar molecules are soluble in polar solvents, as the opposite charges can attract each other, allowing the molecules to mix.
A key component in determining the polarity of a molecule is the polarity of its intramolecular bonds. To do so we need to look at the atoms involved in each bond and the electronegativity difference between them. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.
Polar substances tend to dissolve in polar solvents, and nonpolar substances dissolve in nonpolar solvents. When a solute dissolves in a solvent the individual particles of the solute separate from their neighbours and move between the spaces of the solvent particles.
