Question

electron dot structure of calcium chloride. Identify the nature of above compound. Explain three physical properties of such compounds

Answer 1

Compound formed is "covalent Compound"
properties=
Hygroscopic: Absorbs Moisture from the Air

Diquescent: Dissolves in Absorbed Moisture and the Resultant Solution Resists Evaporation

Solution freezes at low temperature : -59°F (-50.5°C)

EXOTHERMICxothermic heat of solution : Heat is Evolved as Product Dissolves

High Density solutions : Water Weighs 8.3lbs./gal., 25% and 40%
CaCl₂ Solutions Weigh 10.3 lbs./gal. and 11.7 lbs./gal.,

Respectively Reactive source of calcium chloride or chloride ion : These Ions are Useful in a Variety of Chemical Processes

Answer 2

Physical properties: Calcium chloride is found as an odorless white powder, granules or flakes. It has a density of 2.15 g/mL, melting point of 782 °C and a high boiling point over 1600 °C. ... However, its main hazard is due to its desiccating (drying) property and exothermic reaction when it dissolves in water.


Chemical properties: CaCl2 is highly water soluble, hygroscopic (absorbs moisture from air) and deliquescent (absorbs enough water to turn into liquid). Calcium chloride dissolves in water in a very exothermic manner (releasing a large amount of heat). Calcium chloride fully dissociates in water to give calcium cations and chloride anions. In aqueous solutions, the calcium ions can displace other ions in exchange reactions, such as the conversion of potassium phosphate into calcium phosphate:
