Sodium Hydroxide by Lino Gonzalez https://padlet.com/Lino1003/br8f4n0qmcr0 A little bit of this and a little bit of that en-us 2017-05-26 17:01:21 UTC 2025-12-03 10:20:59 UTC hello@padlet.com https://padletuploads.blob.core.windows.net/prod/173765515/f16e6a185603519db8a1e270bc4ac0ea/galensunsword1_squaresize.jpg Names Lino1003 https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174022887 The compound Sodium Hydroxide has many other names. This is mainly because it's is inorganic and man made. The names are 
Caustic soda
Lye
Ascarite
White caustic
SodiumHydrate

Besides this not much else is know about his experiments. After its discovery it was called a fixes alkali for a few years after its discovery. Not much else is known besides that molten Sodium Hydroxide was used in the discovery of Sodium.

Sodium Hydroxide has a interesting origin for its name. However not under the name Sodium Hydroxide but under lye. This is the oldest name for Sodium Hydroxide and lye means "wash stuff" in old English . This was a term used from the 13th century meaning strong soap.]]> 2017-05-26 17:10:07 UTC https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174024251 Chemical Formula and Molecular model Lino1003 https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174026715 Chemical Formula = NaOH]]> 2017-05-26 17:25:20 UTC https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174026715 Bonds Lino1003 https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174027682 As shown in the picture below Sodium Hydroxide is held together by Ionic and Covalent bonds. Oxygen and Hydrogen share a Covalent bond. Sodium and Oxygen share a Ionic bond.]]> 2017-05-26 17:31:40 UTC https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174027682 Uses through History Lino1003 https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174028991 The use of Sodium Hydroxide throughout history and today(it has many more uses today) is for soap. The first evidence of this was in a Arabian book in the 13th century. This book was created by a king of Yemen. Later Europeans started using this method to make soap. As a result of this Nicholas Leblanc a French chemist patented a method of making sodium rich and impure sodium carbonate. This is created when soap is created as a byproduct. ]]> 2017-05-26 17:40:24 UTC https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174028991 Unknown use Lino1003 https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174033384 Due to its low cost and availability, it has been used to dispose of corpses by criminals. Italian serial killer Leonarda Ciancuilli used this chemical to turn dead bodies into soap. In Mexico, a man who worked for drug cartels admitted disposing of over 300 bodies with it. Sodium hydroxide is a dangerous chemical due to its ability to hydrolyze protein]]> 2017-05-26 18:06:13 UTC https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174033384 Uses Lino1003 https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174505938
  • Used in processes to make products including plastics, soaps rayon and
    •         textiles

It can cause severe burns and permanent damage to any tissue that it comes in contact with.Sodium hydroxide can cause hydrolysis of proteins, and hence can cause burns in the eyes which may lead to permanent eye damage.]]> 2017-05-30 21:22:56 UTC https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174507271 How its made Lino1003 https://padlet.com/Lino1003/br8f4n0qmcr0/wish/174507612 Sodium Hydroxide does not occur naturally, but the compound  is  very inexpensive to to make. It is usually produced in a 50% solution through the electrolysis of Sodium Chloride during which Chlorine Gas is also produced. The water can then be evaporated from the solution to obtain the compound in the form of a solid.
