The dissolution of calcium chloride in water has to be classified as physical change or chemical change. Concept Introduction: Physical change: An alteration of substance without changing its composition is called as physical change. The change in state of a substance is the most common physical change. Example: Melting of an ice cube to form liquid water. Chemical change: The conversion of one material to another is called as chemical change (or) chemical reaction . Example: formation of water from hydrogen and oxygen is a chemical reaction because there is difference in the composition of the material at the beginning and end of the process.
