A student was given one packet containing white crystals of sodium chloride and another packet containing white crystals of ammonium chloride for carrying out a project. But he forgot to label the packets. One of his friends suggested him to carry out sublimation on each sample and to identify the sublimable solid. He then helped the student to set up the apparatus for carrying out sublimation and then jointly carried out sublimation of each sample separately.
A. Define sublimation.
B. What are sublimable solids? Give two examples of sublimable solids.
C. State the values demonstrated by the fellow student in helping his friend to identify the samples.
