Profile of a Pure Substance: Water
Boiling Point: Water boils at 100 degrees Celsius.
Color: Water is colorless.
Combustibility: Water is non-combustible.
Density: Water has a density of 1 gram per cubic centimeter.
Ductility: Water is not ductile.
Hardness: Water is not hard as its hardness is measured as zero on the Mohs scale.
Lustre: Water has no lustre.
Malleability: Water is not malleable.
Reactivity: Water is chemically unreactive.
Solubility: Water is highly soluble in polar solvents and solutes such as sugar, salt and acids.
Viscosity: Water has a low viscosity at room temperature.
To create a profile of a pure substance or mixture, let's choose water.
1. Boiling point: Water has a boiling point of 100 degrees Celsius at standard atmospheric pressure.
2. Color: Pure water is colorless, although it can appear slightly blue due to the absorption and scattering of light.
3. Combustibility: Water is not combustible and does not support combustion. It can even be used to extinguish fires.
4. Density: The density of water is approximately 1 gram per cubic centimeter at standard temperature and pressure.
5. Ductility: Water is not a ductile substance as it cannot be drawn into thin wires.
6. Hardness: Water is not considered hard or soft as it is a liquid. However, the hardness of water can refer to its mineral content, such as calcium and magnesium ions.
7. Lustre: Water does not have a lustre because it does not reflect light in a characteristic way.
8. Malleability: Water is not malleable as it is a liquid and cannot be shaped or molded without the use of a container.
9. Reactivity: Pure water is not highly reactive, but it can act as a solvent and participate in chemical reactions under specific conditions.
10. Solubility: Water is known as the "universal solvent" and is highly soluble in many substances, including salts, sugars, and gases.
11. Viscosity: Water has a relatively low viscosity, meaning it flows easily. It becomes less viscous at higher temperatures and more viscous at lower temperatures.
