You know that a chemical change has occurred when the chemical composition of the material changes and a new substance is produced Just like we defined a set of physical properties for substances, we can also define a set of chemical properties Chemical properties are simply the set of chemical changes that are possible for that substanceTo identify a chemical property, we look for a chemical change A chemical change always produces one or more types of matter that differ from the matter sspresent before the change The formation of rust is a chemical change because rust is a different kind of matter than the iron, oxygen, and water present before the rust formed13 Physical and Chemical Properties – ChemistryExample 1 Classify each of the following as either a physical property, or a chemical property: a) The boiling point of water is 100 o C b) Oxygen is a gas c) Sugar ferments to form alcohol Solution a) Although this property describes a change, this change does not involve a change in substance H 2 O remains H 2 O despite what state it is in Thus, this is a physical prop13 Physical and Chemical Properties – CHEM 1114 – For example, changing the color of a metal does not change its physical properties However, in a chemical reaction, a color change is usually an indicator that a reaction is occurring The reaction above is that of the rusting of iron \[\ce{4Fe + 3O2 + 6H2O \rightarrow 4Fe(OH)3}\nonumber \]Chemical Change vs Physical Change Chemistry LibreTexts
