Ammonium iodide is the chemical compound nh4i. It is used in photographic chemicals and some medications. [1] it can be prepared by the action of hydroiodic acid on ammonia. It is easily soluble in water, from which it crystallizes in cubes. It is also soluble in ethanol. It gradually turns yellow on standing in moist air, owing to decomposition with liberation of iodine.

Aluminium sulfate, written as Al2(SO4)3 or Al2O12S3, is a widely used industrial chemical. It is sometimes incorrectly referred to as alum, as it is closely related to this group of compounds. It occurs naturally as a rare mineral millosevichite, found i.e. in volcanic environments and on burning coal-mining waste dumps.

It is frequently used as a flocculating agent in the purification of drinking water[1][2] and waste water treatment plants, and also in paper manufacturing. Aluminium Sulfate is used in water purification and as a mordant in dyeing and printing textiles. In water purification, it causes impurities to coagulate which are removed as the particulate settles to the bottom of the container or more easily filtered. This process is called coagulation or flocculation. Properties
