Alums are soluble in water.
Alums are soluble in water.
Alum is also soluble (less) in Methanol and Ethanol.

Water soluble things are all the things that get dissolved in water completely and homogeneously. A few common examples are salt, sugar, alum, copper sulphate and powdered milk.
Salt crystals generally grow faster than alum crystals because salt is more soluble in water and forms crystals more quickly. Alum crystals tend to grow slower due to their lower solubility 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.
Alums are useful for a range of industrial processes. They are soluble in water; have an astringent, acid, and sweetish taste; react acid to litmus; and crystallize in regular octahedral. When heated they liquefy; and if the heating is continued, the water of crystallization is driven off, the salt froths and swells, and at last an amorphous powder remains. Potassium alum is the common alum of commerce, although soda alum, ferric alum, and ammonium alum are manufactured. Aluminum sulfate is sometimes called alum in informal contexts, but this usage is not regarded as technically correct.

Vinegar and alum can be used together as part of a pickling solution for preserving fruits and vegetables. However, adding water to this mixture may dilute its effectiveness. It is recommended to follow a specific recipe when using these ingredients together to ensure desired results.
The water molecules spread out as temperature increases, which allows the alum to dissolve more readily. Conversely, as temperature decreases, the water molecules become more compact which causes the alum to be less soluble.
