Alum is a type of chemical compound that is commonly used in everyday and industrial applications. You'll find alum in everything from baking powder and toothpaste to cosmetics and some fire extinguishers, but there are also various types of alum with different use cases.
Usually, when you hear about alum it is in reference to potassium alum, which is the hydrated form of potassium aluminum sulfate and has the chemical formula KAl(SO4)2·12H2O.
However, any of the compounds with the empirical formula AB(SO4)2·12H2O are also considered to be alum. Sometimes alum is seen in its crystalline form, although it is most often sold as a powder. Potassium alum is a fine white powder that you can find sold with kitchen spices or pickling ingredients. It is also sold as a large crystal as a "deodorant rock" for underarm use.
Alum refers to a collection of chemical compounds that are hydrated sulfate salts of aluminum and usually one other metal.
Common forms of alum include hydrated potassium aluminum sulfate, ammonium aluminum sulfate, and sodium aluminum sulfate
What is the usage of the Alum in our daily life? Common forms of alum include hydrated potassium aluminum sulfate, ammonium aluminum sulfate, and sodium aluminum sulfate. The different compounds have different functions. They are very common in my life, Today I want to share some comments below.
l Alum, also known as potassium aluminum sulfate, can be used to purify water, Mixing up few ounces of clean and ideally warm water with ~1 tablespoon of alum, allow it to dissolve as much as possible, and then add that to 1 gallon of your brown water. Within 20 minutes, the alum powder will have bound to the sediment and caused it to sink to the bottom, yielding astoundingly clear water
l Alum Powder can also help in relieving Canker Sores, as a Water Purifier and to Reduce Body Odor.Alum Powder is very effective to reduce Foot Odor.
l Preserving Cut Hydrangea Blooms: Dipping cut hydrangeas in alum is one of the most popular methods of preventing wilt. After cutting, simply dip a small section of the hydrangea stem into the alum powder before putting the flower in a vase. It is believed that this process will help the flowers with water uptake.
l Alum mixed with wax has been used by women to remove unwanted hair.
When mixed with water or rosewater, it forms a paste that can be applied to the skin. Once dried, it is gently rubbed off, taking unwanted hair with it It is also beneficial for tightening and whitening of the skin due to its astringent property. Alum causes cells to shrink and removes excess oil from the skin making it effective for the reduction of acne scars and pigmentation marks.
l What is the purpose of adding alum to water during the process of purification? Do you know ? Alum removes the heavy stones and other insoluble substances from water . Alum removes the suspended clay particles from water.Alum is also an ingredient in styptic pencils, another shaving product that manufacturers make by fusing potassium alum with potassium nitrate. Styptic pencils are anti-hemorrhagic agents that treat shaving cuts by aiding clotting and quickly sealing the wound.
l Alum products can also cause mild poisoning if an individual ingests them, which may lead to nausea, vomiting, or an upset stomach. However, these symptoms should resolve quickly, and eating or drinking may reduce their effects
In all ,i think that you wan to know How Is Alum Produced?
Several minerals are used as the source material to produce alum, including alum schist, bauxite,
The specific process used to obtain the alum depends on the original mineral. The resulting material is kept moist and exposed to air until it turns to a powder, which is or extracted, with sulfuric acid and hot water. The liquid is decanted, and the alum crystallizes out of the solution.
