Answer 1

Nothing

Answer 2

to add to what Presh said,

lol.

Answer 3

Heat the solution to concentrate it then leave it in a warm place then partially evaporate solution and allow to cool filter off crystals , pick out crystals. Dry crystals with filter paper

Answer 4

Heat the solution to concentrate it leave it on a warm place the partially evaporate solution and allow to cool filter off crystals, pick out crystals,dry crystals with filter paper

Answer 5

Heat the solution to concentrate it, then leave it in a warm place, then partially evaporate the solution and allow to cool filter off crystals. Pick out the crystals, then dry the crystals with filter paper.

Answer 6

Heat the solution to concentrate it/ leave in a warm place / partially evaporate solution and allow to coolfilter off crystals / pick out crystals dry crystals with filter paper

Answer 7

*Heat to concentrate the solution
*Allow the concentrated solution to cool to form Crystal's
*Filter the crystals
*Wash and dry crystals between filter paper

Answer 8

Yes, that is correct. To summarize:

1. Heat the solution to concentrate it.
2. Allow the concentrated solution to cool to form crystals.
3. Filter the crystals from the solution.
4. Wash the crystals with a small amount of cold water to remove any impurities.
5. Dry the crystals between filter paper to remove any excess water.

Answer 9

Heat the solution to concentrate it, then leave it in a warm place, then partially evaporate the solution and allow to cool filter off crystals. Pick out the crystals, then dry the crystals with filter paper
