This is the limit of solubilty at a given temperature and pressure.
The lower pressure of the suction flask would cause the filtrate to boil. If this happened, the material in solution would be deposited over the walls of the flask.(From Techniques and Experiments for Organic Chemistry by Addison Ault)
What rocks contain crystals?
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
Pencil 'lead' does not contain crystals. It is a mixture of the element carbon (in the form of graphite) and clay.
In some cases it does contain crystals that formed prior to the eruption.
At 20 0C a water solution with a sodium chloride concentration higher than 36,09 g/100 ml is a saturated solution.
no
yes
No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.
No. Pure volcanic glasses contain no crystalline structure.
Well the formula is CuSO4
By definition, yes. In contrast, aphanitic rocks do not have visible crystals.
