Solubility is the ability of a substance to dissolve in a solvent. Water is a polar solvent.

Step2: Analyze each material

• Sand is a non - polar solid with large particles and is insoluble in water.
• Sugar is a polar compound. It forms hydrogen bonds with water molecules and dissolves.
• Food dye is usually water - soluble as it is designed to disperse in water - based solutions.
• Plastic is non - polar and hydrophobic, so it does not dissolve in water.
