Some substances dissolve when you mix them with water. When a substance dissolves, it looks like it disappears. But in fact it has just mixed with the water to make a transparent (see-through) liquid called a solution. When you mix sugar with water, the sugar dissolves to make a transparent solution. Salt dissolves in water too. Heat can help some substances dissolve faster in water. Salt, for example, will dissolve quicker in hot water than in cold water. Substances that dissolve in water are called soluble substances.
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.
