property of water is that it is an excellent solvent. This is because of the chemical composition and physical attributes of water. Since water is polar‚ it allows water molecules to become attracted to different molecules. The attraction can be so powerful that it can disrupt the attractive forces of the different molecules. For example‚ water can be heavily attracted to salt that it can disrupt the forces that hold sodium and chloride‚ therefore dissolving it. The second property of water is its high
