Mix the following chemicals and have them dissolved in isopropyl alcohol to temporarily corrode aluminum dust as a science project. The chemicals that need to dissolve in the alcohol are: calcium carbonate powder: 5 percent (percent by volume), sodium acetate: 2 percent solution, and ammonium thiocyanate:2 percent solution. These need to be dissolved in a 40 percent solution of the isopropyl alcohol. I have all the needed lab equipment. Can you explain what will happen to the aluminum dust when it comes in contact with these chemicals. The aluminum dust is mixed with a binder on a cardboard paper to cover information. The goal of this science project is to see if these chemicals can temporarily corrode the aluminum dust and reveal the information thats on the cardboard paper. CT
