Surface Chemistry

This topic highlights the importance of learning the concepts of surface chemistry. It also describes the various uses of surface chemistry in various fields of science.

In this topic, we will learn about the phenomenon of adsorption. It explains the terms adsorbat, adsorbent, positive and negative adsorption. It also discusses the difference between adsorption and absorption.

This topic talks about adsorption. It can be defined as the adhesion of atoms, molecules, or ions from substances irrespective of their states of matter, to a surface. We will also learn how it differs from the term absorption.

This topic talks about the process of catalysis. We will learn in detail how in this process a chemical triggers a reaction between two other chemicals, but does not take part in the reaction itself.

This topic talks about how colloids can be classified based on multiple factors. Here we will learn one of the most common method of classifying colloids is by identifying the phase of the dispersed substance.

This topic explains to us the nature of emulsion, which is one of the common colloids. It is a mixture of multiple liquids, which are immiscible under normal situations due to liquid-liquid phase separation.

This topic explains some electrical and chemical methods used for preparation of colloidal solution with pictorial illustrations. Here, we will also discuss the process of converting a precipitate into a colloidal solution.

In this topic, we will learn the definition and importance of purifying a colloidal solution. Here, we will also discuss the process of dialysis, electro-dialysis and ultrafiltration in detail with the help of pictorial illustrations.

In this topic, we will discuss different properties of colloidal solution in detail with the help of real life observations.

This topic gives us a detailed picture about the colloids that are around us. Here we will understand how colloids can occur in natural environment too.
