Give a reason why sublimable and non- sublimable substances can be separated easily but two sublimable substances cannot.
Answers
Sublimable substance = substances which turn directly from solid to gas.
Non - sublimable = Substances that undergo through the three states of matter.
We can easily separate sublimable and non - sublimable substances can be separated since:
The sublimable substance escapes first in form of gas.
The non - sublimable substance remains in the container.
If both substances are sublimable they will both evaporate and thus it will be difficult to separate them.
Answer: a sublimable and a non sublimable substance can be separated by heating the mixture. The sublimable substance will evaporate and settle at top of funnel. But two sublimable substance can't be separated easily from one another. After heating both substances will evaporate so they cant be separated easily
