Article On Louis Joseph Gay Lussac

Biography & contributions

Louis-Joseph Gay Lussac was born on December 06, 1778 – died on May 09, 1850. Lussac was a French chemist and physicist and he was best known for his formulation of Gay-Lussac Law.

Lussac analyzed the composition of Earth's atmosphere at different altitudes. He was the co-discoverer of boron. In collaboration with Louis Thenard, he developed a method for quantitative elemental analysis. Lussac recognized iodine as a new element. He developed an improved version of the burette. Lussac was the first person to Coin the terms pipette and burette. He showed that different gases are dilated in the same proportion when heated from 0° to 100°C.

Lussac worked on alcohol-water mixtures, which led to the degrees Gay-Lussac used to measure alcoholic beverages in many countries.

Gay-Lussac Law

Gay-Lussac's law explains the pressure of a fixed amount of gas at fixed volume is directly proportional to its temperature in kelvins

V = k T

Facts about Boron element

Boron is a semimetal of main Group 13 of the periodic table, essential to plant growth and of wide industrial application. Boron is electron-deficient, possessing a vacant p-orbital. It has several forms, the most common of which is amorphous boron, a dark powder, unreactive to oxygen, water, acids and alkalis. It reacts with metals to form borides. Boron compounds are also used as fertilizers in agriculture, and in sodium perborate bleaches.

Boron is an important dopant for semiconductors, and boron-containing reagents are used as intermediates in the synthesis of organic fine chemicals. Boron is similar to carbon in its capability to form stable covalently bonded molecular networks. Boron fibers are high-strength, lightweight materials that are used chiefly for advanced aerospace structures as a component of composite materials, as well as limited production consumer and sporting goods such as golf clubs and fishing rods.

Health benefits of boron includes

  • Building strong bones
  • Treating osteoarthritis
  • For improving thinking skills
  • Muscle coordination
  • For eye wash

Facts about iodine element

Iodine is a mineral that is important nutrient for the body. Iodine is found in range of foods, the richest sources being fish and dairy products. Iodine is important for the production of thyroid hormones. Iodine is present naturally in soil and seawater. Iodine based biocides are used in industrial applications such as paints, adhesives, wood treatment and metalworking fluids.

Iodine is important in human nutrition, as the body needs to have a certain quantity of iodine to avoid goiter disease, thyroid malfunctioning and potential mental retardation and abnormal growth in developing fetuses.

It is extensively used in the pharmaceutical industry, as a raw material for x-ray contrast media and antiseptics, as well as a catalyst or reagent in the synthesis of several active pharmaceutical ingredients such as antibiotics, corticosteroids and cardiovascular drugs.

About 400 tones of iodine escape from the oceans every year as iodide in sea spray or as iodide, hydrochloric acid and methyl iodide, produced by marine organisms. Iodine is extracted from natural brines and oil brines, which have up to 100 ppm of the element.
