How can you make pure crystals of alum from impure alum?
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
Why should you not wash alum crystals in water?
Alum crystals are made of aluminum potassium sulfate, and are usually made by slowly dehydrating an aqueous solution of aluminum potassium sulfate. So, when you put water back onto a dried crystal, you will begin to dissolve it again.
What happens when you add alum to water?
crystals form
Which two crystals grow fastest?
Alum crystals and sugar crystals grow at the same rate at an increasing time rate making them grow the fastest
How big are alum crystals after growing for 2 weeks?
Adding alum to hot tap water until it no longer dissolves, will create a solution that will allow crystals to form as it evaporates. The size the crystals will be for 2 weeks will depend on growing conditions and if any solution is left.
How does hydrated potassium alum visually compare to the anhydrous form?
Alum crystals turn into a solid mass of anhydrous alum
Do salt crystals grow faster than alum crystals?
No, the alum grows faster.

What cations can be used to make alum crystals?
either Aluminum or Boron are used in the synthesis of alum crystals
How would you test for potassium and sulfate ions in the alum?
by adding acids in alum crystals
How does alum affect paper?

How long to make alum crystals?
it depends on how big you want it. if u only do the process once then only a couple of hours
Do alum crystals grow better in dark or light?
The dark
What are alum crystals made of?
they are made of cmpounds of ion matter and matrons
