Abstract: Against the backdrop of the Snowflake Castle collapse and through the dialogue between Little Snowflake and the Doctor, this paper introduces the main components, principles of action, and applications of snow melting agents. Using snow melting agents as an example, it further explores the concept of colligative properties of dilute solutions, their related applications, and the methods of using snow melting agents. The aim is to familiarize readers with the concept of colligative properties in physical chemistry and to promote the concept of environmental protection.

Key words: Snow melting agent, Colligative properties of dilute solution, Green chemistry
