Food Preservation is the method or process of protecting the food from any kind of spoilage after it has been prepared. This process is continuing from the past till now, the only difference is that the techniques have been changed or developed a bit recently. It includes different types and varieties of food processing like […]

Unacademy presents a bird’s eye view of the main Chemistry topics for all IIT-JEE aspirants. Hence, whether it is a quick revision or a detailed conceptual study, our professional teachers make things easy and effective for hardworking students. So, today, Unacademy brings to you some detailed but crisp notes on hydrochloric acid. It is a

The preparation of buffer solution includes a mixture of a weak acid and its conjugate base, or a poor base and its conjugate acid.  The preparation of buffer solution is used to help maintain a pH, resisting alterations in the pH value of the solution. A tiny bit of an alternate acid or alkali is

Before diving into a base buffer, we should know what a buffer solution is? The buffer solution is a mixture of a weak acid and its base conjugate or a weak base and its conjugate acid. Buffer solutions are used to help maintain a stable pH value of another solution mixed with the database. Buffer

The acid in the buffer neutralises the hydroxide ions. It neutralises them with water when a strong base is applied. The buffering effect is highest at the acid (or alkali) pKa. The pH of a (sodium) CH3COOH buffer solution made from one-to-one acetic acid and sodium acetate (for example) is approximately 4.7 (close to the

Sample preparation refers to the process of selecting a representative piece from a larger amount of material and preparing it to be studied or analysed. The small amount ideally should represent the larger amount of the material. Sample preparation or sampling has significance in analytical chemistry since it initiates all kinds of analysis and underlies

Chemical reactions are characterised by chemical changes that result in the formation of new compounds when certain conditions are met. We can better understand chemical reactions between different elements or compounds if we use chemical equations to aid in our understanding. These reactions are represented by chemical equations, which show both the reactants and the

The potentiometer is a basic component of many digital devices. It is a variable resistor that is measured in ohms. A voltage is applied to the wiper of a potentiometer, and the resistance of the circuit is determined by the length of the wire leading to the wiper. There are four types of potentiometers:  Rotary

Introduction This article will elucidate the critical concepts related to physisorption and its characteristics. We have introduced physisorption and its attributes. Physical bonding of Gas molecules with the solid and liquid surface is known as Physical absorption or physisorption. This article will also help you understand the basics of physisorption and its characteristics, the difference

The concept of adsorption is divided into 2 different categories i.e. Physisorption and Chemisorption. Before diving into the detailed characteristics of both these types, let us know what Physisorption and Chemisorption stand for.  1: Physisorption: Physisorption can be termed as the condition when the adsorbate is held onto the surface of the adsorbent by weak
