How would you obtain pure crystals of the salt?
You can obtain smaller and purer crystals by means of using precipitation or using the bigger crystals, because it is better to get them big, then cool them to make them small.
How can you make pure crystals of alum from impure alum?
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
Do you need to separate any matirials to get thorium?
To obtain pure thorium metal it is necessary to separate thorium from other elements.
Why covalent crystals r opaque?
Covalent crystals are not necessarily opaque. Think of diamond, pure quartz crystals, pure aluminium oxide crystals these all are colorless and transparent.
How would you separate an alcohol-water solution into pure alcohol and pure water?
distillation
