The pentahydrate (n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [10] while its anhydrous form is white. [11]
It might not have been a feed supplement; if the pigs got their water from a pond, the copper sulphate might have been kept there to put into the pond to kill algae.
