1 Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. 2  The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.
Hydrophobic liquids like oil will not dissolve in hydrophilic liquids like water. They are immiscible, meaning they won't form a homogeneous solution if you mix them. In a â¦ ny case, MOLECULES THEMSELVES don't DISSOLVE in water. The ions in ionic compounds like salt become dissociated from each other in water, and they do this more easily in polar (hydrophilic) liquids than they do in hydrophobic ones. But even when a hydrophilic liquid dissolves in water the molecules making up that liquid generally do not.
