Answer Details
Ammonium chloride can be separated from its mixture with common salt by sublimation.
Sublimation is a process in which a solid changes directly into a gas without passing through the liquid state. Ammonium chloride has a higher vapor pressure than common salt, which means that it can be converted into a gas more easily than common salt. When ammonium chloride is heated, it sublimes, or changes directly from a solid to a gas, leaving behind the common salt.
To separate ammonium chloride from its mixture with common salt, the mixture is heated. The ammonium chloride sublimes and is collected as a gas, while the common salt remains behind as a solid. The ammonium chloride gas can be collected and condensed back into a solid form by cooling.
This process is used to purify ammonium chloride and is also used in the laboratory to separate mixtures of solids that can be sublimed.
In summary, ammonium chloride can be separated from its mixture with common salt by sublimation, which involves heating the mixture to convert the ammonium chloride directly from a solid to a gas, leaving behind the common salt.
