It's best to print the Word doc to PDF and attach it directly. Links can be broken over time, and Word attachments can contain macros.MightyCatt said:
Got it, I will remember that. The original lab instructions contain safety information on a different page, these instructions are just for me to follow them step by step and so I don't let lost in the paragraphs of the original instructions.berkeman said:
You will need aluminum foil, potassium aluminum sulfate (alum), distilled water, a heat source, a beaker, a stirring rod, a funnel, and filter paper.
Cut the aluminum foil into small pieces to increase the surface area, which helps it dissolve more quickly in the solution.
Heat the distilled water in a beaker until it is near boiling. Gradually add the aluminum foil pieces and stir continuously until the foil is completely dissolved. This may take some time, so be patient.
Once the aluminum foil is dissolved, allow the solution to cool to room temperature. Then, place the solution in a refrigerator to further cool it. Crystals will start to form as the solution cools. Filter out the crystals using a funnel and filter paper.
To ensure the purity, you can recrystallize the Alum. Dissolve the initial batch of crystals in a small amount of hot distilled water and allow it to cool slowly. This process can be repeated if necessary to obtain purer crystals.
