Class 11

Aluminium oxide is also known as alumina, and its chemical formula is Al2O3. It is sometimes also known as alundum, aloxide, or aloxite. It is an amorphous material, has no odour, appears white, and is inert. This compound is insoluble in water and thermally unstable. Also, it reacts with both acid and bases alike; therefore, […]

Introduction This topic educates the learners on Sulphur and its allotropic forms. Here, we will discuss Allotrope of Sulphur,  Allotropic forms of Sulphur, and how these Sulphur Allotropic forms are prepared. This article will also help you to understand the basics of Sulfur, the Allotrope of Sulphur, and which is the most stable allotropic form

An important aspect of Chemistry is Phosphorus, a non-metal. There are various allotropic forms of Phosphorus that exist in nature. The most important forms of phosphorus are categorised as black Phosphorus, red Phosphorus, and White Phosphorus. In this particular topic, we will learn about the Allotropic forms of phosphorus forms along with their nature and

Carbon is the most important part of chemistry. With the capability of forming four covalent bonds at a time, carbon can form many other elements. Having a thorough understanding of carbon is necessary to learn chemistry precisely. Allotropy is the phenomenon used to describe the other corresponding elements or substances of the same state and

A buffer solution can be defined as a mixture formed by combining a weak base with its conjugate acid or a weak acid with its conjugate base. When you add either an acid or a base to a buffer solution, it doesn’t modify its pH. A buffer solution can be of two types—acidic buffer solution

Froth flotation is a process of concentration which separates materials based on their association with water and density. It is mostly used to separate the desired mineral component from a gangue.  It has other applications in the practical field such as, separating plastics, sewage water treatments, and recycling paper. The process requires several reagents to

When it comes to substances that are classified as acids or bases, there are three major categories to consider. According to the Arrhenius definition, an acid produces H+ in solution and a base produces OH- in solution. Svante Arrhenius developed this theory in 1883, and it is still in use today. Theoretical proposals for two

The word acid is derived from ‘acidus’, which means sour. This is because of the characteristic of acids to produce a sour taste when added to water. An acid is a substance that can donate protons or hydrogen ions and accepts electrons in return. Acids have a hydrogen atom bonded to them that can dissociate

There are acidic and basic solutions all over the world. Except for water, virtually every liquid we come into contact with on a daily basis contains acidic and basic characteristics. Vinegar is a dilute solution of acetic acid, which belongs to the class of acids. An arrhenius acid is an acidic substance that produces hydrogen

Ionization of a compound is referred to as the splitting of neutral compounds into ions. As per the Arrhenius theory, the compounds that form H+(hydrogen) ions after dissociation in the medium (aqueous) are called acids. On the other hand, the compounds that form OH- ions after dissociation in the aqueous medium are called bases. The
