I'm trying to prepare a lab for my students where they synthesize alumI have measured out 1 gram of aluminum foil and torn it into small piecesI added 25 ml of 3M KOH to the aluminum foilAll the labs I have looked at say that after a few minutes a reaction will take place and it will turn blackFor me, nothing is happeningIt just sits thereAny suggestions? I'm using Food Lion brand aluminum foilI just made the KOH solution.
You can simply add more insulation over whatever it is you haveBlown-in is probably the cheapest, but you have to get a contractor for thisRoll out bats cost more, but you can save by doing it yourself.
older type of insulation is rock wool was a new idea, then but not very good go with a Blown fiberglass insulation the thicker the better
According to this description the KOH solution has to be hot for the reaction to happenDid you try heating it? chemlab.truman.edu/CHEM130Labs/AlThe only other thing I can think of is that there might be a protective coating on the foil, but that's unlikely.
