If three methods are used to separate a suspension of sand in a solution of ammonium chloride and sodium chloride so as to obtain all three substances. Which order should these three methods be? The methods are Filtration, Sublimation and Evaporation.

well, start off by showing you know which substance gets removed by which process. if you know how the process works then it will be easy to figure out the arrangement.

 

we won't just give a straight answer for homework but we will get you to do it. and make you get it right.

Yup, IA is right. You just need to know what is the basis of each process (i.e. distillation on temperature point), and the rest will be a piece of cake!
