Introduction Acid and base are the two-term terms that you would learn from the beginning of mid-school education. Well, we all know by now that acids and bases are two different levels of potency of a liquid. With the help of indicators, we can know whether the fluid is acidic or basic. Beverages are of […]

Chemical stoichiometry, Chemistry, Class 11, IIT JEE, Some Basic Concepts in ChemistryThe reaction of sulphuric acid (H2SO4) with water and alcoholic compounds produces heat. It is made out of sulphur, oxygen and hydrogen. Many industries use the chemical compound for treatment of ores, in manufacturing fertilisers etc. The odourless and colourless liquid reacts with water, sugar, metals like zinc and delivers different formations. Following its vast industrial applications

Chemical stoichiometry, Chemistry, Class 11, IIT JEE, Some Basic Concepts in ChemistryA buffer is a liquid that can withstand considerable pH changes when added to a small quantity of acid or alkali. The pH of acid buffer solutions is a little less than 7. It’s usually created using a weak acid and one of its salts (commonly referred to as conjugate). Acidic buffer solutions are typically
Every day, we encounter liquids that have acidic and basic properties. The only exception, in this case, is water. The particular acid-base characteristics set them apart from each other. Carl-Axel Arrhenius defines an acid as a compound that yields hydrogen cations when dissolved in water. The strength of an acid or a base is determined

Chemical stoichiometry, Chemistry, Class 11, IIT JEE, Some Basic Concepts in ChemistryAn acid-base titration is a quantitative analysis of acids and bases in which an acid or base of known concentration neutralizes an acid or base of unknown concentration; in this process, an acid or base of known concentration neutralizes an acid or base of unknown concentration. Visual indicators, pH electrodes, or a combination of the

Chemical stoichiometry, Chemistry, Class 11, IIT JEE, Some Basic Concepts in ChemistryThe world of chemistry has all the chemical aspects of the universe explained by it. The atoms, ions and chemical charges continuously connect and form new ‘chemical species’. Such is the formation of complexes in chemistry. The formation of complexes elucidates the interactions of ions or metals. To understand the formation of complexes, we need

Chemical stoichiometry, Chemistry, Class 11, IIT JEE, Some Basic Concepts in ChemistryThe act of courtship is comparable to the establishment of bonds. Atoms move closer together, attract each other, and progressively lose a small portion of their mass to the other atoms. Hybridisation, or the study of bonding, is significant in chemistry. During bonding, what happens to the atoms? The concept of hybridisation holds the key

Atomic and molecular masses, Chemistry, Class 11, IIT JEE, Some Basic Concepts in ChemistryWhen Classical mechanics failed to apply in microscopic particles like electrons, protons, atoms, molecules, etc. since it ignored the concept of dual behaviour of matter, especially for subatomic particles and the uncertainty principle, the branch of science that deals with the dual behaviour of matter and interaction of subatomic particles, Quantum mechanics was introduced. It
A vernier caliper is an instrument that is most commonly used for a variety of exact measurements. A vernier caliper is a tool used in the physics lab to precisely measure the lengths of small objects that would be impossible to do with a meter scale. A vernier caliper’s main use is to measure an object’s internal and external
Quantum numbers are a collection of numbers used to describe the position and energy of an electron in an atom. There are four types of quantum numbers: the principal, azimuthal, magnetic, and spin quantum numbers. They are used to determine the values of the conserved quantities in a quantum system. Electronic quantum numbers (the quantum
