is that copper(II)sulphate in liquid state exist?

what does "glacial" mean?

[suzi9spal]

I think not, because copper(II) sulfate decomposes as temperature increases, losing the last water molecules at 200°C.
When it gets to that anhydrous form, you can heat it further to about 600°C, where it decomposes into copper(II) oxide (CuO) and sulfur trioxide (SO3).

what does "glacial" mean?

You could use a contemporary English dictionary to begin to figure this one out on your own.  I don't know if you've just read, "glacial spring water" and want a chemical definition.  However, I'm going to assume you've just encountered glacial acetic acid, and that means pure acetic acid.  Acetic acid freezes at around 18°C, which is ambient for laboratories sometimes, and you'll want to know if your reagent is going to be a solid block in the bottle.
