Some Basic Concepts of Chemistry

A Clear Explanation on percentage composition and empirical and molecular formula

Composition in terms of percentages Compounds are defined as having a percentage composition if the amount of each element is proportional to the total number of individual elements contained in the compound multiplied by 100. In this case, the quantity is expressed in terms of grammes of the constituent parts. The percent composition of a […]

A Brief Note on Uses of Hydrochloric Acid

The most common name for hydrochloric acid is muriatic acid. When hydrochloric acid gas dissolves in water, hydrochloric acid is produced. This hydrochloric acid is very volatile and strong, having a pungent smell. With the membrane process, distilled hydrochloric acid is isolated from water. Hydrochloric acid is an essential laboratory substance, and in its gaseous

A Brief note on Oxoacids of Phosphorus

Phosphorus reacts with oxygen to generate a range of chemicals, and several of these are oxoacids. A phosphorus oxoacid is composed of phosphorus and oxygen, at least one hydrogen atom bonded to oxygen, and the loss of one or more protons results in the formation of an ion. Acids that contain oxygen are called oxyacids.

A Brief Note on Limitations of VSEPR Theory

Although the VSEPR model is effective at forecasting molecular geometry, it is ineffective at predicting the morphologies of isoelectronic species and transition metal complexes. In this model, the relative sizes of substituents and stereochemically inactive lone pairs are ignored.. As a result, hefty d-block species that experience the stereochemical inert pair effect cannot be studied

A Brief Note on Important Points of Chemical Reactivity

Reactivity is a chemistry term that describes how easily a substance can conduct a chemical reaction. The substance can react individually or with other atoms or compounds, and the reaction is usually accompanied by the release of energy.  The most reactive elements and compounds have the potential to spontaneously ignite or explode. They usually burn

Empirical Formulas and Molecular Formulas

Earlier, chemical formulas were determined by the mass of elements that form a molecule but later, two important formulas were formulated- molecular formula and empirical formula. The empirical formula is the simplest ratio of the number of atoms in the molecule, on the other hand the molecular formula is the number of individual atoms in

Enthalpy of Dilution in Thermodynamics

Enthalpy of dilution refers to how much energy it takes to move one component from one place to another in an equal-pressure solution, or how much energy it takes to move one component from one place to another. In this case, the component is a pure liquid when it first comes into contact with the

Evaluated with the Help of Geometry in Three Structures

This term comes from the words “gê,” which means “earth,” and “métron,” which means “a measure.” is, along with arithmetic, one of the older subfields that fall under the umbrella of mathematics. It is concerned with the qualities of space that are related to distance, form, size, and the position of figures in relation to

Example of gases

A gas is a condition of material that has neither a definite volume nor a defined shape. In other words, a gas takes on the shape and volume of the container in which it is contained. Condensation of gases into liquids or ionization of gases into plasma. The particles in a gas are further apart

Factors Affecting Melting Point

Melting Point The melting point of a material or a compound is being used to evaluate its cleanliness or impurities. The melting temperature of a chemical compound is the point at which a chemical compound transitions from a solid to a liquid state. In the case of a solid substance, when heat is supplied gradually,
