Properties
Physical Properties – describe a substanceChemical Properties – describe the “ability of
a substance to change into something newCharacteristic properties – are physical or
chemical properties that are unique to a particular substance. They can be used to identify the substance.

Characteristic properties
Physical or chemical properties that are specific to a particular PURE substance or group of PURE substances
These are used to help identify unknown substances
These are most often quantitative

Physical Characteristic Properties
Density – the amount of matter in a substanceMagnetism – force of attraction to a magnetSolubility – ability of a substance to dissolve
in another substanceMelting Point – temperature that a solid
changes to a liquidBoiling Point – temperature that a liquid
changes to a gasFreezing Point – temperature that a liquid
changes to a solid

Magnetism – difficult to calculate – usually compared to another magnetic or non-magnetic substance

The ability of a substance to ….
Examples:
React with another substance to produce a specific result
Produce a specific color change
Burn in the presence of a flammable gas
Create a popping sound or “explosion”
Cobalt chloride turns from pink to blue when there is water present
A glowing splint bursts into flames when there is Oxygen present
A flaming splint produces a popping sound in the presence of Hydrogen

If you are identifying Unknown Substances
You must have at least two characteristic properties AND various other physical and chemical properties in order to identify an unknown substance.
