24 views

Yes, CaCl2 (Calcium Chloride) is highly soluble in water. It dissolves readily, resulting in a solution that can get quite hot, showcasing an exothermic reaction. This property makes it useful in a variety of applications, such as de-icing roads, in brine for refrigeration plants, and in dust control. Its solubility also makes it an important chemical in several industrial and scientific processes.

FAQs & Answers

  1. What happens when calcium chloride dissolves in water? When calcium chloride dissolves in water, it dissociates into calcium and chloride ions, releasing heat due to an exothermic reaction.
  2. Why is CaCl2 used for de-icing roads? CaCl2 is used for de-icing roads because its high solubility in water creates a solution that lowers the freezing point, melting ice effectively even in very cold temperatures.
  3. Is calcium chloride safe to handle when dissolved in water? Calcium chloride solution is generally safe to handle with proper precautions, but it can cause irritation to skin or eyes, so protective gear is recommended.
  4. How does the exothermic nature of CaCl2 dissolution affect its applications? The heat released during CaCl2 dissolution helps accelerate processes like freezing point depression and aids in dust control by drying surfaces faster.
