well i want to know if can change the shap of the crystal or how to change it while you are still making it, for example while you are making it is there any way to make the crystal square or roundplz help
Yes you can,once the crystal is a solid,you dissolve it in a suitable solvent at elevated temperature.Then after you remove any undissolved material or impurities by filtration,the filtrate is cooled slowly to allow crystals to form.The slower the crystals grow and the larger they become,the purer the substance.That experiment demonstrates crystal growth from an aqueous solution.Using potassium aluminum sulfate(known as alum)The crystals shape si determined by the directions that grow the slowest.
