Some Basic Concepts in Chemistry

Colloids are found mainly in nature and can also be made by humans. Since colloids have such a wide range of industrial applications, it’s critical to have a comprehensive categorisation system in place. A dispersed phase and a dispersion medium constitute colloids. Colloids are also called colloid dispersion because in a colloidal solution the particles […]

A sol is a colloid with suspended particles in the solvent medium. There is a wide variety of particle sizes in the sols. These are prepared by different chemical processes such as condensation or dispersion. They have the tendency to show the Tyndall Effect (scattering of light through particles present in the solvent). Forms of

All colloids have two phases, i.e., a dispersed phase and a dispersion medium. The dispersion medium is of three categories: liquid, gaseous, and solid, and the colloidal particles are scattered throughout the medium. These colloids are foams, emulsions, liquid aerosol, solid foam, gel, and solid sol. Most of the dispersion mediums are liquid and made

INTRODUCTION Empirical, molecular, structural, and projection formulae are the most prevalent types of formulas. An empirical formula is made up of symbols that represent the components in a compound, such as Na for sodium and Cl for chlorine, as well as subscripts that indicate the number of atoms in each constituent element. (Unless the number

A colloid is a heterogeneous system in which one substance is dispersed (dispersed phase) as very fine particles in another substance known as the dispersion medium. The primary difference between solution and colloid is the particle size. In solution, the constituent particles are ions or small molecules. In colloidal solutions, the dispersed phase may consist

The relationship between the volume of a gas and its pressure was named Boyle’s law after Robert Boyle, who was an Irish scientist. He was the first to research the quantitative link between a gas’ volume and pressure in 1962. Robert Boyle was also an eminent natural philosopher, chemist, physicist, and inventor. Meaning of Boyle’s

Avogadro’s Law When applied to gases, Avogadro’s law (also known as Avogadro’s principle or Avogadro’s hypothesis) states that the total number of atoms or molecules in a gas (that is, the amount of gaseous substance) is directly proportional to the total volume occupied by the gas at constant temperature and pressure. Avogadro’s law is closely

Emulsion is a mixture of two or more liquids having minute or ultramicroscopic droplets dispersed through one another, as defined in physical chemistry. Either spontaneously or mechanically, (such as agitation) emulsions are created from the liquid components, provided that the liquids being mixed have no or minimal mutual solubility.  Emulsions are commonly used in several

Gas laws are a group of physical principles that predict the behaviour of gases. Many of those laws pertain to ‘ideal’ gases in closed systems at degree Centigrade and pressure (STP). However, their concepts should be used to understand and influence the spread of physical and chemical processes within the body. Every application of gas

Colloids are mixtures of chemically microscopic components that are insoluble in nature and the particles of one substance are dispersed into another substance. The particles that are suspended in a colloidal mixture can vary between one to one thousand nanometers. For a mixture to be categorised as a colloid, the particles that are dispersed into
