|
Attributes and characteristics
that describe what the chemical species is. o Examples: color, melting point, density |
physical properties
|
|
|
Attributes and characteristics
that depend on how a chemical species reacts. o Examples: solubility, miscibility, chemical reactivity You will determine various physical and chemical properties of three liquids. • Density: Ratio of mass to volume. Density = Mass (g) Volume (mL) • In a mixture, the species with lower density will “float” and the species with higher density will “sink”. o In an oil & water mixture, the less dense oil will float on top of the more dense water. |
