Introduction This article will tell us about the difference between the two types of cells: Electrolytic cells and Galvanic cells. Cells They are devices that either produce electricity or in chemistry, it is basically a setup or arrangement in which chemical reactions take place. Based on this difference cells are divided into two types : […]

Introduction Strong acids are substances that on dissociation release a vast number of hydronium cations ( H+or H3O+). Strong acids also have a large value for Ka (dissociation constant for acids). According to many scientists and the theories proposed by them, Strong acids are further described in numerous ways. Theories for strong acids 1. Bronsted

1. Weak electrolyte definition Weak electrolyte are those electrolytes that have a low degree of dissociation at higher concentrations and hence their conductivity increases with an increase in dilution. Consequently the number of ions in the total volume of electrolyte increases. Examples CH3COOH (Acetic Acid), H2CO3 (Carbonic Acid), NH3 (Ammonia), H3PO4 (Phosphoric Acid), C6H5COOH (Benzoic

Know in one minute about Electrolytic cells Electrolytic cells are a type of electrochemical cell that uses electricity to initiate chemical reactions. It consists of elements like electrodes, power sources, and electrolytes. The electrodes are of two types- anode and cathode. Cathode is the junction at which reduction takes place while the anode is the

Introduction Minerals are natural substances that are extracted from rocks found either on the surface or inside the earth. Based on their natural properties, they are categorized into two groups namely metallic minerals and non-metallic minerals. Metallic minerals are minerals that contain metal elements such as iron, copper, zinc, and lead. There is a crucial

Introduction Strong Acids and Bases are those acids and bases which completely ionized into ions (H+ and OH- ions) in aqueous solutions. Strong Acids Before diving into the topic, let us discuss about Acids. Acids are substances that release H+ ions on dissociation in an aqueous solution or accept electron pairs. These are often sour

Know in one minute about molar conductivity Molar conductivity refers to the conducting power of ions in a solution. Its unit is S.m2.mol-1 (Siemens X meter square per mol). The molar conductance of a solution depends upon its nature, concentration, and temperature. As the concentration decreases, molar conductance increases. Its formula is λm = Κ

Introduction Anion exchange vs cation exchange is the two forms of ion-exchange chromatography. These are the two chemical methods used to separate molecules according to their net surface charge. There are some differences between these two chemical methods. An ion is an atom or molecule. When an atom is charged positively or negatively by accepting
