The Types of Emulsions

The colloidal dispersion of two non-miscible liquids, where one liquid acts as the medium of dispersion and the other as a dispersed phase, is known as an emulsion. In simple words, an emulsion is a mixture that consists of two liquids that don’t mix with each other.  The word emulsion is derived from Latin, which […]

The Concept of Hybridisation Involving s, p and d orbitals

When two atomic orbitals integrate together to form a hybrid orbital in a single molecule, the redistribution of orbital energy of individual atoms occurs, resulting in the equivalent energy of an orbit. Hybridisation is the term used to describe this process. The hybrid orbitals are the new orbitals that are formed as a result of

Solar Cell

A solar cell is an electrical device that, through the photovoltaic effect, converts the energy of light directly into electricity. The photovoltaic effect is both a physical and chemical phenomenon. When exposed to light, it is a type of photoelectric cell, which is defined as a device whose electrical characteristics such as current, voltage, or

Silicon Tetrachloride, Silicates, Zeolites, and Silicones

Zeolites and silicones are basically types of microporous. Formation of this type of microporous happens with the help of three-dimensional crystalline solids of aluminum silicate. A small opening side is fixed in zeolites. From this opening side, small molecules enter through it easily. But large molecules can not banter from this opening side. This is

Pure Substances and Mixtures

Matter refers to anything that possesses mass and also has weight. It can be distinctly divided into two groups: pure substances and mixtures. Pure substances are also further broken down into elements and compounds. Mixtures generally represent a physically combined structure which can be separated into their original constituents. A chemical substance is made up

Properties of Radiation

Radiation is a sort of energy that comes from somewhere and travels through matter or space. Light and heat are both examples of radiation. Because it has enough energy to take an electron from an atom and change it into an ion. Properties of radiation: Radiation can be absorbed by substances along its path. For

Properties of Liquid – Vapour Pressure and Viscosity

Liquids belong to one of the three phases of matter. The other two are solids and gases. The nature of the liquids helps us understand their function, composition and structure. It is essential to study the properties of liquids, as they help you learn about their chemical makeup and how it affects the liquid’s behaviour

Properties of Gases

Gases are defined as substances generally found in the gaseous state. They are largely compressible and feature intermolecular distances. As compared to solids and liquids, the gas particles are at larger distances from one another. Note the gas substance does not have any fixed shape, size, or volume. However, they occupy the space they enter.

Properties of Emulsion

There are various mixtures in Chemistry made by combining different substances having different or similar mediums. The emulsion is an important type of colloid. These are used for various purposes in daily life. A lot of emulsions used are man-made and are created to perform specific functions. Furthermore, emulsions are also used in manufacturing processes
