Alum, any of a group of hydrated double salts, usually consisting of aluminum sulfate, water of hydration, and the sulfate of another element. A whole series of hydrated double salts results from the hydration of the sulfate of a singly charged cation (e
Also known as chromium alum, this dark violet compound has been used in tanning, and it may be combined with other types of alum to produce crystals that are lavender or purple. Aluminium potassium sulphate This substance is also known as papermaker’s alum by its other name, aluminum sulfate...
plaster, the gypsum is completely dehydrated at a high temperature, and such chemicals as alkali sulfate,alum, orboraxare added. Hair or fibre and lime or clay may be added to plasters during manufacture. The plaster coats, except for some finish coats, are sanded.See alsoplaster of paris....
Chromium salts such as chrome alum (KCr(SO)42) and chromium(III) sulfate are used in the process of leather tanning. During the tanning process, chromium creates cross-links between the collagen fibers in the animal hide. Although the compounds used for tanning do not include chromium in its...
I’ve asked myself the same question, so I decided to do some research to find out everything I could about those mysterious little packets. It turns out they have a number of useful applications around the house, from preventing rust to defogging your windshield!
Changes if any = Aluminium Sulphate (Al2(SO4)3) is white crystalline solid in its anhydrous form and in its solution form it appears as a colourless liquid. It is also called Filter Alum or Dialuminum trisulfate.
It is in purple crystals form and is soluble in hotwater. In high concentration, it can become toxic. When mixed with glycerine, it will start a fire. Applications of Potassium Dichromate The major application of K2Cr2O7is in the potassium chrome alum preparation, a compound, which is extensiv...
Thus, thallium does form an alum, but in doing so it replaces the M+ ion, rather than the expected metal atom M3+, in M+M3+(SO4)2∙12H2O. Soluble thallium compounds are toxic. The metal itself is changed to such compounds by contact with moist air or skin. Thallium poisoning, ...
