Introduction Human kidneys perform the vital function of eliminating metabolic wastes from the body. Any failure of the kidneys to naturally perform their functions would become a matter of life or death for the patient. This is where ‘dialysis’ comes into the picture as a lifesaver. Dialysis is derived from the Greek words ‘dia’ meaning […]

Dalton’s law of partial pressure has a lot of applications. It is one of the most conventional methods to measure the pressure exerted by two gases and calculate the partial and total pressures. With the help of this law, we understand that pressure in a container consisting of a mixture of gases could be found

The term “diluted” or “concentrated” is used to describe the concentration of a solution; it is a qualitative way of expressing how concentrated the solution is. Dilute solutions are those in which the amount of solute is relatively small, whereas concentrated solutions are those in which the amount of solute is relatively high. We don’t

One of the most popular measures used to quantify the concentration of a solution is molarity (M), which shows the number of moles of solute per litre of solution (moles/Liter). Molarity is a unit of measurement that can be used to determine the volume of a solvent or the amount of a solute. The formula

Introduction The number of moles of a solute is divided by the number of kilograms of the solution’s solvent to get molality. In contrast to molarity, which is determined by the volume of the solution, molality is defined solely by the mass of the solvent in the solution. Because volume changes with changes in temperature

A solution is a mixture of solvent and solute. A solvent is generally a liquid in which various materials or solutes dissolve to form a solution. A solute is a substance dissolved in a solvent and forms a solution. The size of the substance or particles may vary such that the particles may be seen

The microscopic, distributed insoluble particles of one material suspended in another are colloids (colloidal solutions and colloidal systems). Particles suspended in a colloid vary in size from one to a thousand nanometers (10-9 metres). The suspended particles of a combination must not sink to the bottom of the container to be considered a colloid. In

Introduction A mixture in which a substance with microscopically spread insoluble particles (this is known as the dispersed phase) is suspended throughout another substance (known as the dispersion medium) is termed as a colloid in chemistry. Colloids are broadly classified into lyophilic and lyophobic colloids based on their affinity with each other. As the name suggests, lyophilic colloids are lovers of liquid,

Colloids are found mainly in nature and can also be made by humans. Since colloids have such a wide range of industrial applications, it’s critical to have a comprehensive categorisation system in place. A dispersed phase and a dispersion medium constitute colloids. Colloids are also called colloid dispersion because in a colloidal solution the particles
