When a salt is added to a polar solvent like water, the ions interact with the solvent molecules via ____, which overcome the forces originally holding the ions together.
The ions are then isolated and stabilized in solution via these interactions, and when this occurs for most of the salt compound, it is considered in ____ that solvent.
Due to the nature of the interaction between ions and solvent molecules, a concentration of ions can be dissolved ____in water than in alcohol.

Answer 1

Answer:

The words are: (2) ionic bonds; (3) ion-dipole forces; (4) soluble; (8) higher

Explanation:

-Salts are composed of ions that form a tightly packed and ordered network, which is called a crystal lattice, and it is held together by ionic bonds.

Explanation: salts are ionic compounds, which are composed by oppositely charged ions (cations and anions) which are bonded each other by ionic bonds, in an ordered arrangement, often a crystalline solid.

-When a salt is added to a polar solvent like water, the ions interact with the solvent molecules via ion-dipole forces, which overcome the forces originally holding the ions together.

Explanation: the molecules of a polar solvent are dipoles because they have dipolar momentum (a difference in charge due to a electronegativiy difference). When a salt is dissolved in a polar solvent, it dissociates in ions. So, the resulting interactions between these species are ion-dipole forces.

-The ions are then isolated and stabilized in solution via these interactions, and when this occurs for most of the salt compound, it is considered soluble in that solvent.

Explanation: the ions in solution are surrounded by solvent molecules which stabilizes them. A salt which is enterely dissolved in a solvent is soluble in that solvent.

-Due to the nature of the interaction between ions and solvent molecules, a concentration of ions can be dissolved higher in water than in alcohol.

Explanation: water molecules have unique properties that make water an universal solvent. Due to these properties and its polarity, water can dissolve larger quantities of salt than other polar solvents such as alcohol.
