Mole concept

Before we begin to explore all the aspects of the various colloids present in surface Chemistry, let us first understand the concept of colloids. What are colloids? Colloids are particles that have a diameter between 1 to 1000 nanometers. It consists of a mixture of particles. These particles are spread throughout the solution in an […]

A meniscus is a curve in the surface of a molecular substance (water) when it encounters another material. Imagine water holding to the inside of a glass to get a sense of what it’s like. Adhesion is responsible for a meniscus, and this has to do with the high surface tension of water. The molecules

The rule that states that the total pressure exerted by a mixture of gases equals the sum of the partial pressures exerted by each individual gas in the mixture is known as Dalton’s law of partial pressures (or vice versa). The overall pressure exerted by a mixture of two gases A and B, for example,

Dalton’s law of partial pressure states that in a mixture of non-reacting gases, the total pressure exerted equals the sum of partial pressure of an individual gas. Therefore, the pressure imposed by a single gas in a mixture of gases is known as its partial pressure. For example, if a container contains a combination of

It is common knowledge that anything that has mass and can occupy space is called matter. Matter is made up of elements of more than one type. No element except the noble gases can exist independently in nature. They usually occur as a group of atoms. There is some sort of force holding the group

Interactions between two or more molecules are called intermolecular interactions, while interactions between molecular atoms are called intramolecular interactions. Intermolecular interaction occurs in all types of molecules or ions in all states of matter. They range from strong long-range electrical attraction and repulsion between ions to relatively weak dispersion forces that have not yet been

There are different kinds of forces, i.e., attraction and repulsion forces which are responsible for the combination of colloidal particles. The intermolecular forces between the colloidal particles play a significant role in the applications of colloids in many industrial purposes. Interaction forces support in identifying the chemical behavioural aspect of the colloids and it also

Gases are one of the fundamental states of substances. Gas is a collection of molecules that are separated by a significant distance. The ideal gases are those in which the molecules collide in elastic ways. In these perfect gases, there are no intermolecular attraction forces. However, there are no such things as perfect gases in

Gas is a collection of particles in rapid motion. The particles are in constant collision all the time. A gas takes up the shape of whatever contains it. An ideal gas has zero interactions among its particles, and it also obeys the ideal gas law. The importance of this concept is that it is used

Introduction: In chemistry, orbital hybridisation (or hybridization) is the idea of blending atomic orbitals to shape new hybrid orbitals (with extraordinary energies, shapes, etc., than the component atomic orbitals) appropriate for the pairing of electrons to shape chemical bonds in valence bond theory. Hybrid orbitals are beneficial withinside the clarification of molecular geometry and atomic
