Description
Ελληνικά: Θερμαίνουμε σε δοκιμαστικό σωλήνα τρίμματα γαλαζόπετρας και παρατηρούμε εξαγωγή υδρατμών και μετατροπή του χρώματος σε ανοιχτό μπλε και μετά σε άσπρο.Ο λόγος είναι ότι η γαλαζόπετρα είναι ένυδρος θειικός χαλκός και όταν θερμαίνεται αφαιρούνται τα μόρια νερού με την μορφή υδρατμών ,οπότε αλλάζει το χρώμα της γαλαζόπετρας σε άσπρο.Εάν ξαναπάρει νερό ξαναγίνεται σκούρο μπλε.
