  • When you heat a mixture of ammonium chloride and sand in a test tube for five minutes, ammonium chloride shall convert into gaseous form while sand shall remain in it’s solid state.
  • This is a method of separating ammonium chloride and sand through a process known as sublimation.
  • By ammonia turning into gaseous state directly, it shall have sublimated. Therefore, sublimation is the process in which solids turn into gas directly without turning into liquid form first.
  • Here is the equation of ammonium chloride sublimation: NH4Cl(s) → NH3(g) + HCl(g).
