The working principle of snowmelting agents
Thread Content
I would like to ask everyone about the working principle of snowmelting agents.
Common de-icing agents are generally sodium chloride or a mixture of sodium chloride and calcium chloride. The freezing point of water is 0 degrees. When de-icing agents are added, they dissolve in the snowmelt water, forming solutions of sodium chloride or calcium chloride. Since the freezing points of sodium chloride and calcium chloride are significantly lower than 0 degrees. As sodium chloride and calcium chloride dissolved, the snow also melted.
Simply put, de-icing agents lower the melting point of snow, making it easier for it to melt
