Explain why water can separate and disperse ionic solids such as nacl but most other solvents are unable to do so

A solvent is a chemical substance that has the ability to dissolve other chemical compounds, called solute, to form a solution.                

Solvents can be polar and non-polar in nature.

In general, polar solvents dissolve only polar solute molecules and non-polar solvents dissolve only non-polar solute molecules.

Highly polar solute molecule such as ionic compounds like NaCl and sugars, dissolve only in highly polar solvents with a large dielectric constant like water.

Therefore, because of the high dielectric constant of water, ionic compounds can be easily separated and dispersed.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
