The Magic of Chemiluminescence

INTRODUCTION  While thinking about light,the human mind jumps to a conclusion that sources like Sun,glowing bulbs or even a campfire,basically which involves the presence of heat to glow that is burning fuels,heated filaments or nuclear fusion. But what if we say that nature and chemistry have their own unique way of making light without heat? For that, let's look into the fascinating world of chemiluminescence,where chemical reactions create radiant light on their own by turning invisible molecular changes into visible beauty. Sup WHAT IS CHEMILUMINESCENCE? The emission of light as a direct product of a chemical reaction is known as chemiluminescence. It is not like a flame or incandescent bulb which glows because of heat ,however this process entirely skips the heating part. The working of this process can be simplified as follows: ●First Step:   The chemical reaction occurs which produces a high-energy intermediate that is an unstable molecule. ●Second Step: ...

Major Inventions in Chemistry Part-II

ANALYTICAL CHEMISTRY INVENTIONS  1. Spectrophotometry (19th century) -Spectrophotometry is considerd as  a powerful tool for chemical analysis as it is a scientific technique which can be used to measure the interaction between light and matter. -It functions by measuring the amount of light which can be absorbed or transmitted by a sample, that can provide valuable information about the sample's composition, concentration, and properties. -It works on the following Principle: • Light source : Lamp or laser are used as a light source which emits a beam of light and that beam is directed towards the sample. • Sample preparation :Dissolving a sample in a solvent or placing it in a specialized container give us a prepared sample for observation. • Light absorption or transmission : As soon as the light beam interacts with the sample, the amount of light absorbed or transmitted is measured. • Detector : Photodiode or photomultiplier tube devices are used to...

INORGANIC CHEMISTRY INVENTIONS  1. Haber-Bosch Process (1909):   -It is a method that brought revolution in the production of ammonia. Nitrogen (N2) and hydrogen (H2) gases are used to produce ammonia (NH3).  -German chemist Fritz Haber and engineer Carl Bosch in the early 20th century developed this process which had a profound impact on the production of fertilizers, explosives, and other chemicals. - In 1904, by using a combination of nitrogen and hydrogen gases Fritz Haber experimented the production of ammonia. -However in 1909,He achieved a breakthrough as he was able to develope a process which by using high pressure and temperature converted nitrogen and hydrogen into ammonia. -Commercial-scale production of ammonia was made possible in 1913 by the efforts of,an engineer at BASF, Carl Bosch who jointly worked with Haber thus scaling up the process. -The ammonia produced by this process is used to manufacture fertilizers like amm...

Natural Phenomena

>What is a natural phenomena? The observable events which occur naturally without any human intervention is known as natural phenomena. For example: weather,gravity,biological processes,germination,rusting etc. Types of phenomena:- - Physical phenomena  -Chemical phenomena  -Biological phenomena  -Astronomical phenomena  -Geological phenomena  -Meteorological phenomena  >Importance of natural phenomena  -Growth of a plant being a natural phenomena help humans get food from them. -Volcanic eruptions and oceanic currents affect the global climate  -Formation of clouds and rainbows can impact the environment in many ways. In this blog, we are going to discuss some of the startling  natural phenomena. >Formation of a rainbow 🌈  ● Rainbow appears like an arc of different colors in the sky when sun shines after a heavy rain. It can be seen in the section of sky which is opposite the sun. ● It's formation obeys the process...

Wonders of Physics

Classical Physics Wonders Gravity: It is the force by which any body or planet draws object towards its center. It is this force that keeps us on ground and work as an aid for planets to be in their orbits around sun. Sir Isaac Newton discovered Gravity when he saw a falling apple while thinking about forces of nature.He determined each and every object has Gravitational Force in it. Gravity has many important functions like : - On earth Gravity gives weight to physical objects. -It helps to guide the growth of plants. -It influence the fluid circulation in organisms. - Moon's gravity is responsible for sublunar tides in the oceans. Electromagnetism : It is the force by which electrically charged particles interact with each other in the presence of a magnetic field. The field can be static,slowly,changing or in the form of a wave,these waves are transverse in nature. Hans Christian Oersted ,a Danish Scientist discovered electromagnetism in 1820. He, through his exper...
