How To Dissolve Aluminum Foil
Step ii: Dissolve the Aluminum | ||
| Place the pieces of aluminum foil in a 250 mL beaker. | | |
| Measure out 5 mL of one.four M KOH in a graduated cylinder. | | |
| And so pour the KOH solution into the beaker containing the small pieces of foil. | | |
| Place the beaker with the KOH and small pieces of foil on a hot plate underneath the private fume hood at your lab demote. It should take about five - 10 minutes for the aluminum to deliquesce with the hot plate set at medium heat. Stir occasionally with a drinking glass stirring rod. |  | |
| The solution should plough a dark charcoal gray colour. If the liquid drops to ¼ the initial volume while heating, add some distilled h2o carefully to bring the level of the liquid back up to ½ of the original volume. Stir occasionally with a glass stirring rod. |  | |
| After 5- ten minutes on the hot plate, the glass beaker will exist hot. Do non endeavor to remove the chalice with your bare hands or you lot volition get burned. Apply a pair of chalice tongs or an oven mitt to remove the beaker from the hot plate once the aluminum has dissolved. Gear up the beaker bated to absurd on your laboratory bench. |  | |
| Mensurate 6 mL of 6 Grand sulfuric acrid (H2SO4) in a make clean graduated cylinder. When your beaker is cool to the touch (this may take a few minutes), slowly add the 6 mL of the sulfuric acid while stirring with a glass stirring rod. This should be done under the hood. |  | |
| A pulpy white substance will class; with stirring, however, it should misemploy. This white solid is the precipitate of Al(OH)3 (south) discussed in the introduction. |  | |
| Continue to stir until your solution is translucent. |  | |
