Physical state
Calcium chloride can be found in solid state at room temperature, and is available as flakes, granules, and in the powdered form.
Taste, color, and odor
Calcium chloride is salty to taste. Hence, it is added to many food products like canned vegetables, pickles etc. In the solid form, this compound is white in color, while in the liquidated form, it is colorless. This is an odorless compound.
Density and Solubility
The density of calcium chloride is 2.15 gm/cm3. It is soluble both in inorganic solvents like water, as well as organic solvents like ethanol.
Electrical conductivity
Usually in a molten state, it is a good conductor of electricity.
Thermal conductivity
Calcium chloride is a bad conductor of heat.
Boiling point
Its boiling point is as high as 1935°C.
Hygroscopy
It is hygroscopic in nature and absorbs moisture from air. If exposed to open air, it tends to turn into liquid. That is why, it is often called a deliquescent substance.
Melting point
It has a low melting point, which means it can be dissolved at a very low temperature. The value of melting point of this compound is 772°C.
