What type of brine is commonly used for skating and hockey rinks?

Calcium chloride is commonly used for skating and hockey rinks because it has several advantageous properties that make it suitable for this application. It has a lower freezing point than water, which helps maintain a solid ice surface even under warmer conditions. This is particularly important for outdoor rinks or environments where temperature fluctuations are common. Additionally, calcium chloride can help to prevent the formation of ice particles, leading to a smoother surface that is essential for safety and performance in skating and playing hockey. Its hygroscopic nature allows it to absorb moisture from the air, which can help reduce surface problems like ice melt in warmer weather or when humidity is high. These characteristics make calcium chloride a preferred choice for ensuring quality ice conditions at rinks.
