Why is water a better solvent for salt than oil is?

Water is better solvent for salt as compared to oil because water is a polar solvent. The water molecules are tend to attract each other and other polar molecules also because of their polarity. The oil molecules are non polar hence, they will not attract to any other polar molecules. Therefore, water is a better solvent for salt as compared to oil.

Because water is polar and oil is non polar, their molecules are not attracted to each other. The molecules of a polar solvent like water are attracted to other polar molecules, such as those of sugar ... Because water molecules are polar, they interact with the sodium and chloride ions.
