The Synthesis of Alum experiment involved combining a piece of aluminum with 3M
potassium hydroxide solution (KOH). The goal of this experiment was to obtain a sample of
alum crystals. This was achieved by mixing a piece of aluminum foil (Al) with the solution to
cause a reaction. A series of filtrations processes took place to separate the alum from the
solution to obtain the crystals. Various tests were conducted to confirm that the crystals were
alum. The result of the aluminum and potassium hydroxide combination was an exothermic
reaction. The aluminum sample underwent ionization. This experiment confirmed the synthesis
process of the aluminum sample.
A piece of aluminum foil weighing 0.98 grams was torn into several smaller pieces and
placed in a 250 mL beaker. 25 mL of 3 molar KOH solution (potassium hydroxide) was poured
into the beaker with the aluminum foil. An exothermic reaction took place as shown by bubbling
