Summary
Calcium chloride desiccant has a wide range of applications due to its good safety.
Calcium chloride can be used as a desiccant, snow melting agent, dust collector, refrigerant, etc. So why can calcium chloride be used as a snow melting agent to melt ice and snow, and what is its snow melting principle?
1.Calcium chloride has the characteristic of dissolving in water and releasing heat, which helps to melt ice and snow.
2.Calcium chloride has a relatively low freezing point when dissolved in water, while sodium chloride has a freezing point of -10 degrees Celsius when dissolved in water, and calcium chloride has a freezing point of around -20 degrees Celsius when dissolved in water. So it is difficult to form ice cubes after using calcium salt melting agents, which is beneficial for snow removal;
3.After the melting agent of calcium chloride is dissolved in water, the concentration of the sample in the water increases, causing the liquid vapor pressure of water to decrease, while the solid vapor pressure of ice remains unchanged. Therefore, in order to achieve the vapor pressure between the two, the ice will melt. This is why calcium chloride can also be used as a snow melting agent to melt snow and ice.
