Introduction Many characteristics make the solution different from the Colloids. The properties can be the chemical nature or the light scattering tendency or even the particle solubility. Not only that but also many things such as the components particle size, nature, and filtration can differ from each other. Each type of mixture has its properties that help in the identification. What are Colloids? Colloids can be found in many things and many forms. The most common example of colloids is the water droplets in the fog. During the fog, those water molecules are dispersed in the gas. In daily life, ... Read More

Introduction Solutions were formed when different types of compounds are mixed. Mainly by the dissolution of solute on a solvent. There are two types of solutions; they are homogeneous and heterogeneous solutions. The solutions that possess uniformity in their properties are homogeneous. While the one which doesn't have any uniformity in their properties are heterogeneous solutions. There are many laws associated with solutions. Raoult's law is one such law. The French chemist François-Marie Raoult discovered Raoult's law in the year 1880 for explaining the ideal solution. This law mainly focuses on the properties of ideal solutions. But it also ...

Introduction Colloids are type particles that contain particles with a size more than atoms and molecules but are small enough to be visible by the naked eye. The studies regarding colloids began in the 19th century itself. In the 1820s Robert Brown discovered the random motion of colloidal particles present in a liquid with the help of a microscope. Which is then called Brownian motion. And it developed because of the bombardment of colloidal particles. Smoke, clouds, etc. are colloids. They are dispersions of solid particles with a size of 1 nm to 0.1micrometre range. And these particles have characteristic ... Read More

Introduction Brownian motion in simple words can be defined as the random movement of dust particles or microscopic particles in liquids or gases( fluids). When observed under a microscope, it was seen that these particles are never still. But it is seen that this movement results due to the particles colliding with each other. This movement was first observed by Robert Brown in 1827. He observed the movement of pollen grains suspended in water under a microscope. He was puzzled to see the movement even though the grains were dead, so he started some other phenomena occurring. But this ... Read More

Introduction Graham's law or also called Graham's law of diffusion was given or established by Thomas Graham (Scottish chemist) in the year 1848. Graham’s law (for both effusion and diffusion) describes that the rate (amount) of (e) effusion or diffusion of any particular gas (g) is inversely (inv.) proportional ($\mathrm{\propto}$) to the square (sq.) root of its molecular weight (m.w.). Graham’s law is useful for separating (distinction) isotopes by diffusion, which is further very useful in the production of atomic (atom) bombs. This law is more accurate (suitable) for molecular type diffusion which further involves the motion of one gas ... Read More

Concentration is a phrase that is widely used in chemistry as well as other related subjects. This is a method of measuring the amount of one material combined with another. This might relate to any form of chemical reaction; however, this is particularly used in the framework of solutions to describe the amount of solute dispersed in a solvent. The quantity of solute that dissolves in a given quantity of solution is determined by the concentration of a solution. It is indeed a macroscopic characteristic that may be represented qualitatively as well as quantitatively. To represent concentration qualitatively, a solution ... Read More

Introduction The phenomenon of freezing point depression discusses whenever introducing a solute to such a solvent causes a lowering of the freezing temp of the solvent. The freezing temp of such a compound seems to be the temp where the vapour pressure of the compound during its liquid phase equals the vapour pressure of the compound within the solid phase. Whenever a non-volatile solute has been dispersed in such a pure solvent, the vapour pressure lowers as per Raoult's Law. As a result, the overall vapour pressure of such a solution would be relatively lower than those of the pure ... Read More

Introduction The Chemical Dihydrogen Monoxide abbreviated as DHMO, is like a water molecule but it's not similar in properties to water. It is a colourless and odourless chemical. It is a dangerous chemical that causes deaths to many American every year due to accidental ingestion. It is present in every river, lake, stream, and reservoir in America. It is a major component of acid rain, the greenhouse effect. DHMO in gaseous form causes burning of the skin. It also causes corrosion and rusting of metals. It is considered an invisible killer. Even though it has so many causes, ... Read More

Introduction Factors affecting solubility are mentioned below as follows − Solutes: The substance which is added to the solvent to dissolve into it. Solvents: The liquid part or major volume part which absorbs the solute particles when added to it. Insoluble: If some stones or sand are added into water and tried to mix it, these solute particles are not dissolved into water hence, the solute (stone or sand) is insoluble in solvent water. Soluble: If a tablespoon of honey or sugar is added into water and tried to mix it, it completely dissolve into water and hence, the ... Read More

Introduction Types of electrophoresis are classification of the processes involves during application of electrical energy to any substance. Electrophoresis is derived from two Greek words, elektron means amber and phoresis means the act of bearing. In 1931, the first work of electrophoresis begins by Arne Tiselius. It was a primitively easy of separating the chemical and molecules analysis. The modern version of this process starts in the 21st century. What is Electrophoresis? Electrophoresis is a method and technique used for separating the RNA, DNA, and protein molecules. The whole process is done on the basis of size of the ... Read More
