Reducing Aire Pressure
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.
You would recrystallize a solid from a solvent pair because if only one solvent was used, then it might be hard to dissolve the solute. In a solvent pair, one solvent would probably be better at dissolving the solute.
The size of the container or vessel used for the solute and solvent would likely not affect the rate of solubility, as long as there is sufficient space for mixing.
Yes, salt dissolving in water is a physical change because it does not involve a change in the chemical composition of the salt. The salt molecules are simply dispersed in the water, but they remain the same chemical substance.
please anyone else can answer this question I'm in hurry pls.

You can eat some kinds of crystals... salt crystals and sugar crystals, for example. It's probably not a good idea to eat, say, quartz crystals, though.
Sugar and salt crystals are probably found in every kitchen.
you have to put it in a dissolving dish and wait over night for it to dissolve in the morning it will probably be dissolved

Diamonds are probably the most well known crystals, but ice is the most common. no what the freak ice isn't a cyrstal... its frozen water =P
Anhydrous crystals are likely to absorb moisture from the air, causing them to become hydrated. This can alter the crystalline structure and purity of the crystals. It is important to store anhydrous crystals in a dry environment to prevent moisture absorption.
Yes, there are graphs showing the solubility of NaCl in water vs temperature and pressure. At room temperature and standard pressure, NaCl solubility is around 36 g per 100 ml water. As temperature increases, solubility also increases. Pressure has a smaller effect on NaCl solubility compared to temperature. A graph can illustrate these relationships visually.
Probably to be prepared for the inevitable, to be more prepared, nevertheless how safe you think you are, always be prepared, and listen to the ones around you with opinions that contradict your own.
Probably I never tried. I'm trying now ;D
It is not safe to consume crystals as they can be toxic and harmful to your health. It is important to be cautious and avoid ingesting any type of crystals as they are meant to be used for healing purposes through other methods such as wearing them, placing them in your environment, or using them in meditation.
