Study Island answer: Water; its polar
Polar solvents such as water, alcohols, and acetone are best for dissolving ionic compounds because they have the ability to break apart the strong ionic bonds in the compound due to their positive and negative charges. This allows the individual ions to be surrounded and solvated by the solvent molecules, leading to the dissolution of the ionic compound.
Polar solvents such as water, methanol, ethanol, and acetone are commonly used to dissolve ionic compounds. These solvents have a high dielectric constant, which helps in overcoming the strong electrostatic forces between ions in the ionic compound, allowing them to dissociate and dissolve.
Ionic compounds do not dissolve well in liquid covalent compounds because their strong ionic bonds are not easily broken by the weaker intermolecular forces present in covalent solvents. The polar nature of the covalent solvents also does not provide sufficient interaction with the ions to overcome the ionic bonding in the solid.
Nonpolar solvents, such as hexane and benzene, do not dissolve ionic compounds because they lack the ability to dissociate the ions due to their nonpolar nature. Ionic compounds require polar solvents, such as water or alcohols, to dissolve and dissociate into their constituent ions.
Ionic compounds are insoluble in organic solvents because organic solvents do not provide the necessary interactions for ionic bonding to be broken and replaced by interactions with the solvent molecules. Organic solvents lack the ability to stabilize the charged ions in the ionic compound, leading to poor solubility.

The typical rule for dissolving substances in one another is that substances most readily dissolve other substances with similar bonds. Alkanes are nonpolar because they have mostly nonpolar bonds. On the other hand, ionic compounds have ionic bonds, which are extremely polar. Therefore, because the difference in bond type, ionic compounds do not dissolve in any alkane.
Ionic compounds have positive and negative ions that easily separate in polar solvents due to the charges interacting with the solvent molecules. The polar solvent molecules surround the ions, breaking the ionic bonds and dissolving the compound.
Sodium chloride (NaCl) is not soluble in organic solvents due to its ionic nature. Organic solvents are typically nonpolar, while sodium chloride is an ionic compound that dissolves readily in polar solvents like water. When mixed with an organic solvent, the strong ionic bonds in sodium chloride prevent it from dissolving and instead it remains as solid particles.
Substances that dissolve in water are typically polar or ionic compounds like salts (such as sodium chloride), sugars (like glucose), and some gases (like oxygen and carbon dioxide). Nonpolar substances, such as oils and fats, do not dissolve well in water.
compounds in the liquid separate into positive and negative charged ions.
CCl4 is a non polar solvent and therefore dissole ionic compounds
