For example: diffusion of bromine vapors in air. Diffusion is the property of matter which is based on the motion of its particles. Diffusion occurs in gases, liquids and solids. Diffusion is fastest in gases and slowest in solids. The rate of diffusion increases on increasing the temperature of the diffusing substance. Diffusion in Gases: Diffusion in gases is very fast. This is because the particles in gases move very quickly in all directions. The rate of diffusion of a gas, however, depends on its density.
Light gases diffuse faster than heavy gases. However, a smell does not travel this fast. This is because its particles collide with each other and with particles of air very frequently.
They change direction randomly when they collide, so it takes much longer to travel from one place to another. Their random motion because of collisions is called Brownian motion. Diffusion can also happen in liquids. This is because the particles in liquids can move around each other, which means that eventually they are evenly mixed.
For example, potassium manganate VII is a purple solid. If you put a crystal of it into a jar of water, the purple colour spreads slowly through the water. This is by diffusion. The slideshow describes what happens. Gaseous particles tend to undergo diffusion because they have kinetic energy. Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy.
Solids, liquids, gases can diffuse in liquid. Diffusion in Liquids: Solids gases and liquids can diffuse into liquids. The rate of diffusion is higher in liquids than that of solids. This is due to the fact that in the liquid state, particles move freely and have greater space between each other as compared to particles in the solid state. Diffusion is a property of liquids and gases. It happens because of the difference in the concentration between the particles.
Generally, the particles move from the area of higher concentration to the area of lower concentration until it is evenly spread out. The materials diffuse into each other because of their free movement of the particles of such materials.
Fractional distillation is the process of separating two or more miscible liquids by distillation, the distillate being collected in fractions boiling at different temperatures. A mixture of two miscible liquids can be separated by the process of fractional distillation.
An example of immiscible liquids is oil and water. Based on the concentration of solute dissolves in a solvent, solutes are categorized into highly soluble, sparingly soluble or insoluble.
Homogeneous solutions are formed when both the solute and solvent are in the gas phase liquid in gas and solid in gas combinations form colloidal dispersions ; when a solvent in the liquid phase is combined with either a solid, liquid or gas solute; or when a solid solvent is combined with a solid, liquid or gas …. The liquids which mix with each other are called miscible liquids. The oil layer is on top of the water because of the difference in density of the two liquids. The density of a substance is the ratio of its mass weight to its volume.
To describe how well liquids mix together chemists use the term miscible. If two liquids are miscible, when they are mixed together, the two liquids will combine to form a homogeneous solution. When a liquid is heated, the atoms or molecules gain kinetic energy. Answer: A liquid solution is a liquid in which a substance has been completely dissolved. Solutions having solute in gaseous state and solvent in liquid state, are called Gas — Liquid Solutions.
For example — Solution mixture of oxygen in water, mixture of carbon dioxide in water. Coca cola, a beverage, is an example of gas — liquid solution, as it has carbon dioxide dissolved in water.
A solution is a homogeneous mixture of solvent and solute molecules. A solution can be liquid, solid, or gaseous.
