Molecular Mass Of Stearic Acid

Carbon is a nonmetallic, tetravalent element that is of great use to humans. Its name is derived from Latin carbo which means charcoal or ember. Fifty-fifty though carbon is only 0.025% of the earth's crust and 0.03% in the atmosphere information technology is of nifty importance to mankind. Carbon's abundance and its ability to form polymer at normal is the reason information technology is ordinarily found in all living forms.

Stearic Acid

Stearic Acid is a long saturated chain of fat acids consisting of 18 carbons. It is sometimes even known as Octadecanoic acrid due to the presence of xviii carbons in the structure and Stereophonic acid. The name stearic comes from the Greek give-and-take stear which ways tallow. The salts and esters of stearic acid are collectively known as stearates.

Information technology is constitute in diverse animals and plants in a combined form. Naturally, stearic Acid is found as a mixed triglyceride or fat along with many other long-chain acids. It can even be found equally an ester of fatty alcohol. Normally it is plant more than in animal fatty when compared to Vegetable fat but this has some exceptions as cocoa butter and shea butter have high quantity of Stearic acid.

Preparation of Stearic acid

Information technology is made from carbohydrates. Stearic Acid is made from fats and oils by saponification of triglycerides using hot water. The Stearic acid used commercially is a mixture of stearic acid, palmitic acid, and a small quantity of palmitic acid. Though a pure grade of Stearic acid can be prepared, commercial use is highly unlikely due to various factors.

Structure of Stearic acid

The molecular formula of Stearic acid is CtwoH36O2 or CHiii(CHtwo)16COOH. The IUPAC proper name of Stearic Acid is Octadecanoic acid.

Physical and Chemical Properties of Stearic acid

  • Stearic Acrid is present equally a white solid.
  • Stearic Acid is odorless in nature.
  • Stearic acid is tallow in sense of taste.
  • The Humid point of Stearic acrid is 721°F at normal pressure.
  • The Melting indicate of Stearic acid is 156.7°F at normal pressure. The melting signal of Stearic acrid is high because it is saturated fat and it takes more than rut to dissociate the structure.
  • It is insoluble in water and it floats on water.
  • The density o Stearic acid is 0.86°F at normal temperature and pressure.
  • It is stable at normal room temperature and pressure level.
  • When it is heated to a higher place the boiling bespeak it decomposes to emit acrid fume and irritating fumes.
  • The pH of Stearic acid is around 5.5. It is a weak acrid much similar all organic acids.
  • The molecular mass of Stearic acid is 284.48 grand/mol.

Uses of Stearic acid

  • Stearic acid is used as a lubricating amanuensis due to its soft texture.
  • Stearic acrid is used in the production of many detergents, soaps, shampoos, and shaving cream products. Easter of Stearic acid is used to produce the pearly effect in soaps and shampoos.
  • Stearate salts of zinc and calcium are used as heat stabilizers.
  • It is even used every bit a food condiment.
  • Used in food packaging.
  • It is used to make insulators.
  • It is used as a negative plate condiment in pb-acrid batteries.
  • It is used in the manufacturing of Candles.
  • It is used in coating metals like aluminum and iron with the help of electrolytic plating.

Sample Questions

Question 1: What are the molecular formula and IUPAC name of Stearic Acrid?

Answer:

The molecular formula of Stearic acrid is CiiH36Otwo or CH3(CHii)16COOH. The IUPAC name of Stearic Acid is Octadecanoic acrid.

Question ii: Explain the physical structure of Stearic acid.

Answer:

Stearic Acrid is nowadays equally a white solid. Stearic Acrid is odorless in nature. Stearic acid is tallow in sense of taste. It is stable at normal room temperature and pressure.

Question 3: What are the humid and melting indicate of Stearic acid?

Answer:

The Boiling point of Stearic acid is 721°F at normal pressure level. The Melting point of Stearic acid is 156.7°F at normal pressure level. The melting point of Stearic acrid is high considering information technology is saturated fat and it takes more rut to dissociate the structure. When information technology is heated to a higher place the boiling point it decomposes to emit acrid smoke and irritating fumes.

Question iv: How is Stearic acrid prepared?

Answer:

It is fabricated from carbohydrates. Stearic Acid is made from fats and oils by saponification of triglycerides using hot water. The Stearic acrid used commercially is a mixture of stearic acid, palmitic acrid, and a small quantity of palmitic acid.

Question v: What is the main source of Stearic acid?

Respond:

Naturally, stearic Acid is establish as a mixed triglyceride or fat along with many other long-concatenation acids. It tin can fifty-fifty be found as an ester of fatty alcohol. Normally it is found more in animal fat when compared to Vegetable fat merely this has some exceptions as cocoa butter and shea butter have high quantity of Stearic acid.

Question 6: List some uses of stearic acid.

Answer:

Stearic acid is used as a lubricating agent due to its soft texture. Stearic acid is used in the production of many detergents, soaps, shampoos, and shaving cream products. Easter of Stearic acid is used to produce the pearly consequence in soaps and shampoos. Stearate salts of zinc, and calcium are used as heat stabilizers. It is even used as a nutrient additive. Used in food packaging.

Question 7: Is Stearic acrid soluble in h2o.

Answer:

The pH of Stearic acrid is around 5.5. It is a weak acid much like all organic acids. The molecular mass of Stearic acid is 284.48 g/mol.
