Adsorption and absorption

Weathering is the term used to describe the process of rocks and minerals dissolving or breaking down on the Earth’s surface as a result of the action of the sun and water. Many agents, including ice, water, acids, salts, animals and plants, as well as changes in temperature, contribute to the process of weathering’s initiation. […]

What is Water Adsorption? Water adsorption at surfaces is critical in materials science, chemical engineering, and even catalysis. Water adsorption, also known as surface hydration, occurs when physically or chemically water adsorb on the surfaces of solids. It is critical for regulating the properties of interfaces, chemical reaction pathways, and catalytic performance in a broad

Adsorption, a term coined by a German scientist, Heinrich Kayser, in 1881, is commonly referred to as a surface phenomenon where the particles of gas, liquid, or solid form a layer over the top surface of the substance they are adsorbed at. Very similar to absorption, both these scientific concepts have a very prominent difference.

A prism is a transparent, smooth flat optical object that reflects light. Because objects with both parallel surfaces polished cannot be considered as prisms, one of their surfaces must be tilted in a prism. Prisms are formed from absorbent materials to the wavelengths for which they were created. Glass, plastic, and fluorite are among the

The attractive force which is exerted upon the surface molecules of a liquid by the molecules beneath the surface tends to draw the surface molecules into the bulk of the liquid and making the liquid assume the shape having the least surface area is called surface tension. Surface tension of water helps creatures mostly of

Surface Chemistry is a branch of chemistry that tells us the characteristics of surfaces or phase boundaries and the chemical changes occurring at a surface or interface. Surface chemistry tells about the phenomena that occur at the surfaces or interfaces. The surface is characterised by separating the bulk phases by a slash. For example, the

Introduction Aluminium chloride is used to make aluminium metal in industry,  also  it has a lot of functions in the chemical industry, especially  as  Lewis acid. Covalently bound solid aluminium chloride (AlCl3) has a low melting and boiling temperature. Hans Christian Oersted, a Danish scientist and chemist, discovered aluminium chloride in 1825.  Structure of  AlCl3 

Aluminium oxide is a compound composed primarily of oxygen and aluminium molecules. It is a colourless crystalline substance that appears naturally in several forms, such as sapphire, which are usually composed of corundum. Alumina, or the most common crystal form of alumina, is corundum. Interestingly, under special conditions, corundum became the gem sapphire. Alumina is

Introduction Soap is a fatty acid salt used to manufacture cleaning and lubricating products. Surfactants, like soaps, are commonly used in the home for laundry, bathing, and other domestic tasks. Soaps are utilised as thickeners, components of certain lubricants, and catalyst precursors in industrial settings. Soap dissolves particles and grime, allowing them to be removed

Introduction:-A soap is a water-soluble compound that is produced through a process known as saponification, which involves the reaction of sodium hydroxide or potassium hydroxide with a vegetable or animal oil to form a soap (fats). Soap Hardness Characteristics – Harder soap that is a dense bar lasts longer than softer soap. Cleaning – The
