MATÉRIEL 2 éprouvettes de 15 mm x 125 mm Un support à éprouvettes Un crayon marqueur Une bouteille compte-gouttes d’eau distillée Une bouteille compte-gouttes d’une solution de sels de calcium Une bouteille compte-gouttes d’une solution d’oxalate d’ammonium
MANIPULATIONS 1. À l’aide du crayon marqueur, numéroter les deux éprouvettes. 2. Verser 20 gouttes d’eau distillée dans l’éprouvette 1. 3. Verser 20 gouttes de la solution de sels de calcium dans l’éprouvette 2. 4. Dans chacune des éprouvettes, ajouter 10 gouttes d’oxalate d’ammonium. 5. Observer ce qui se produit dans les éprouvettes. Noter les résultats.
