Preparation of Colloid Solutions

A colloid is another name for a colloidal solution. It is a heterogeneous solution, but due to the small particle size, it may appear to be a real solution. To distinguish a colloid from a genuine solution, the term ‘sol’, as in colloidal sol, is used instead of the term ‘solution’. Their particles are also […]

Preparation and properties of colloids – Tyndall effect.

Introduction Colloids can be formed by  various techniques involving physical, chemical as well as by using some dispersion methods. These techniques rely on different principles. Let us explore more about these techniques for Preparation of Colloids. Ways of preparation of colloids  Preparation of Lyophilic Sols: For preparation of the lyophilic sol, the dispersed phase is

Phase Transition and States of Matter

The activity of a substance changing from one state to another is called phase transition. Any element or substance can transition from one stage to the next at a specific pressure and temperature combination. For example, when water boils, it changes from a liquid to a gas. In all of these phases, the empirical formula

Partial Pressure

Each gas in a mixture adds to the total pressure of the mixture. The partial pressure is responsible for this contribution. The partial pressure is the pressure that a gas would have if it were in its own volume and temperature. While pressure is usually denoted by the letters P or p, partial pressure is

Nomenclature (Trivial and IUPAC)

When naming chemical compounds, the trivial system of nomenclature does not rely on any predefined laws. Instead, the names are based mostly on the organic compounds’ source or qualities.  For example, under the trivial nomenclature convention, methane was dubbed marsh gas since it was mostly found in marshy places. Formic acid is another example of

Mole Concept Molar Mass and Percentage Composition

An extremely significant component of applied sciences is the investigation of these chemicals and how their composition plays a vital role in our everyday lives and activities. When we talk about atoms and their properties, the concept of a mole is brought into consideration.   To establish the concept of a mole, we will first discuss

Mole Concept Basics

If we’re talking about particles at the atomic (or molecular) level, it’s well known that even one grain of a pure element has a significant number of atoms. This is one of the most common applications of the mole notion. In particular, it concentrates on the unit known as a ‘mole,’ which represents the total

Mole Concept

The mole concept is a convenient way of expressing the amount of a substance in a given amount of space. Almost any measurement can be broken down into two parts: the numerical magnitude and the units in which the numerical magnitude has been expressed. The magnitude of 2 kilogrammes is represented by the number ‘2’,

Mole Concept

Introduction  The term “Mole” was first introduced by Wilhelm Ostwald. The mole concept connects the macroscopic to the molecular or atomic level. As it connects these levels, it allows chemists to weigh and count atoms or molecules. With the help of moles, it becomes easy to measure large objects like elephants by counting and small
