For example salt dissolving in water is usually considered to be a physical change, however the chemical species in salt solution (hydrated sodium and chlorine ions) are different from the species in solid salt. A chemical transition is the result of a chemical reaction, and a physical change occurs where the structure of matter changes but not the chemical identity. Precipitation reactions, particularly ones that produce an obvious colour change, such as Epsom salts and ammonia solution. PDF. This precipitate is evidence of a chemical change. Other commonly held views are that chemical changes are caused by the mixing of substances/reactants or that heat (which is considered to be some form of material) has to be added. Moreover, no new chemical substance is formed because of which it is a physical change. Students have difficulty distinguishing between physical and chemical change, despite formal teaching, and the distinction is somewhat arbitrary.
