L’alumnat va realitzar quatre pr\u00e0ctiques de laboratori:<\/p>\n

1. Identifiquem l’escena del crim<\/b>. Van aprendre a caracteritzar quatre subst\u00e0ncies que es poden trobar a l’escena d’un crim, l’hemoglobina, la glucosa i l’alb\u00famina, que es troben a la sang i el lleixiu com a producte de neteja amb diferents reaccions qu\u00edmiques.<\/p>\n

2. Identificaci\u00f3 de f\u00e0rmacs<\/b>. Van realitzar una t\u00e8cnica de cromatografia en gel de s\u00edlice per a la separaci\u00f3 dels f\u00e0rmacs en una mostra desconeguda segons la polaritat d’aquests.<\/p>\n

3. La qu\u00edmica a casa<\/b>. Van aprendre a diferenciar diferents productes de casa com l’\u00e0cid ac\u00e8tic, l’aigua t\u00f2nica, el lleixiu i l’aigua oxigenada a partir de les propietats \u00e0cides, b\u00e0siques i oxidants de cadascuna.<\/p>\n

4. Rac\u00f3 del fred<\/b>. Van veure la difer\u00e8ncia de refredar amb gel d’aigua, di\u00f2xid de carboni s\u00f2lid (gel sec) i el nitrogen l\u00edquid.<\/p>\n
