Chemical Kinetics Chemical kinetics is the branch of chemistry that deals with the study of the rates at which chemical reactions occur and the factors that influence these rates. It focuses on understanding the mechanisms by which reactants transform into products and the factors that affect the speed of these reactions. Key concepts in chemical…
Standard electrode potential Standard electrode potential, often denoted as E°, is a measure of the relative tendency of a half-cell in an electrochemical cell to undergo reduction or oxidation compared to a standard reference electrode. It represents the potential difference between the half-cell and the standard hydrogen electrode (SHE) under standard conditions. The standard electrode…
EMF Electromotive Force (EMF) is a term used in the field of physics and electrical engineering. It refers to the potential difference or voltage developed between two points in an electrical circuit or an electrochemical cell. EMF is typically represented by the symbol “E” and is measured in volts (V). In the context of an…
Laws of electrolysis The AIIMS (All India Institute of Medical Sciences) entrance exam is a prestigious medical entrance examination in India. While I can provide you with information on the topic of “Laws of Electrolysis” in the Chemistry syllabus, it’s important to note that the syllabus for the AIIMS entrance exam may vary from year…
Electrolysis Electrolysis is a chemical process that involves the use of an electric current to induce a non-spontaneous chemical reaction. It is a technique used to decompose compounds into their constituent elements or ions by passing an electric current through an electrolyte. In electrolysis, an electrolyte is a substance, either in a molten state or…
Kohlrausch’s Law Kohlrausch’s Law, also known as Kohlrausch’s equation or Kohlrausch’s conductivity law, describes the behavior of the molar conductivity of an electrolyte solution at a given concentration. It states that the molar conductivity of an electrolyte can be expressed as the sum of the molar conductivities of its individual ions. Mathematically, Kohlrausch’s Law can…
Electrolytic solutions Electrolytic solutions are solutions that contain ions and can conduct electricity. They are formed by dissolving electrolytes, which are substances that dissociate into ions when dissolved in a solvent, typically water. The ions in the solution are responsible for the electrical conductivity. In an electrolytic solution, there are two types of ions present:…
Redox reactions Short for oxidation-reduction reactions, are chemical reactions in which there is a transfer of electrons between species. In these reactions, one species undergoes oxidation (loses electrons) while another species undergoes reduction (gains electrons). This transfer of electrons is accompanied by changes in the oxidation numbers of the elements involved. Key concepts related to…
Electrochemistry Electrochemistry is the branch of chemistry that deals with the study of the relationship between electricity and chemical reactions. It involves the conversion of chemical energy into electrical energy and vice versa. Electrochemical processes are vital in various fields, including energy storage, corrosion prevention, electroplating, and biological systems. Key concepts in electrochemistry include: The…
Colligative Properties Colligative properties are a set of physical properties of solutions that depend on the number of solute particles present in the solution, regardless of their chemical identity. These properties arise due to the interactions between the solvent and the solute particles. The four main colligative properties are: It is important to note that…
