Question

Which technique is used to separate salt from the filtrate after sublimation of ammonium chloride?

• A. Evaportion
• B. Condensation
• C. Centrifugation
• D. All of the above

Answer 1

Answer: (A)

Evaportion

Evaporation technique is used to separate salt from the filtrate. Common salt does not decompose during evaporation. As the water evaporates, fewer and fewer water molecules are present to keep the salt particles apart. The salt therefore recrystallizes and can be collected.
