Is smoke colloidal and is smoke colloidal why

No, smoke should be tiny solid particles.

The nature of colloids.

1.Tyndall phenomenon (optical properties).

Experiment: Starch colloid, colloid, solution are irradiated vertically with a laser pointer.

Phenomenon: There is a light path inside the colloid, but the solution does not.

Conclusion: The phenomenon of a bright channel formed by the scattering of light by colloidal particles is called Tyndall phenomenon.

Note: This property can be applied to distinguish between solutions and colloids.

2.Brownian motion (dynamic properties).

Introduction: The colloids are small and light, how well it moves in the water.

Experiment: A drop of liquid is placed in water and observed.

Phenomenon: Colloidal diffusion.

Explanation: The colloidal particles are hit by different forces of water molecules in different directions, so the direction of motion changes at every moment, thus forming a disordered and non-stop motion, which is called Brownian motion.

3.Electrophoresis (electrical properties).

Experiment: The colloid is placed in a U-shaped tube with conductivity at one end.

Phenomenon: Darkening of color near the cathode.

Analysis: The color is darkened near the cathode, the colloids are positively charged, and they move towards the cathode under the action of the electric field, the colloidal diameter is small, the surface area is large, the adsorption capacity is strong, and only cations are adsorbed, so they are positively charged.

Conclusion: Electrophoresis: Under the action of electric field, the phenomenon that colloidal particles move directionally to the cathode or anode in the dispersant is called electrophoresis.

No, as mentioned in high school chemistry, there are two substances that are formed in the combustion reaction, one is fog and the other is smoke, fog is a lot of water molecules, and smoke is a lot of solid particles. Colloids have strict classification criteria and refer to solutes with a radius greater than 100 nanometers of solid particles in solution.

Yes, because the particles that make up the smoke are between one and one hundred nanometers, according to the theory are colloids.

Yes, when a beam of light passes through a colloid, it forms a bright "pathway", which is known as the Tyndall effect, and smoke also has this property.

No, colloids are a sticky substance. Contains water, smoke is not.

Smoke is colloidal. When a beam of light passes through the colloid, it forms a bright "pathway", known as the Tyndall effect, and smoke also has this property.

Coloid, also known as colloidaldispersion, is a relatively homogeneous mixture, which contains two different states of substances in the colloid, one dispersed phase and the other continuous phase.

A part of the dispersed matter is composed of tiny particles or droplets, and the dispersed system with a diameter between 1 and 100 nm is colloidal; Colloids are a kind of dispersion systems with a diameter of dispersed particles between the coarse dispersion system and the solution, and this auspicious number is a highly dispersed multiphase inhomogeneous system.

Colloids don't have to be gelatinous and they don't have to be liquids. Such as: iron hydroxide colloid, clouds, preparing for feasts and fog, etc.

Smoke is colloidal. The essence of the colloidal macro line is between 1 nanometer and 100 nanometers in diameter, while the solution is less than 1 nanometer. The distinction between colloidal masking and solution can be judged by Tyndall or elephant, if there is light and there is a light path, it is colloidal, and if there is none, it is a solution.

And on foggy days, light can pass through. So, fog is colloidal.

Colloids are divided into aerosols, liquid sols, and solid sols according to the different states of dispersants.

1. Aerosol: a dispersion system with gas as a dispersant. The dispersed substance can be liquid or solid (e.g. smoke, fog, etc.).

2. Liquid sol: a dispersion system with liquid as a dispersant. The dispersion can be gaseous, liquid or solid (e.g., Fe(OH)3 colloid).

3. Solid sol: a dispersion system with solid as a dispersant. Its dispersions can be gaseous, liquid or solid (e.g. tinted glass, smoky quartz).

Be. Smoke is an aerosol and is a dispersion system with gas as a dispersant, and its dispersion can be liquid or solid, (such as smoke, fog, etc.). Colloid, also known as colloidal dispersion, is a relatively homogeneous mixture that contains two different states of substances in the colloid

Dispersed phase, continuous phase.

The colloidal root indicates that the state of the dispersant can be divided into: aerosol, liquid sol, solid sol, and the different dispersions can be divided into: particle colloid, molecular colloid.

Smoke, clouds, and fog are aerosols, colored glass and crystals are solid sols, protein solutions and starch solutions are liquid sols, starch colloids and protein colloids are molecular colloids, and soil is particle colloids.

Colloids are used in agricultural production, medical and health care, daily life, physical geography, Huaiyu industrial production, wastewater treatment, etc.

1. The properties of colloids:

Tyndall phenomenon can occur, resulting in polysedimentation, electrophoresis, dialysis, adsorption and other properties.

Colloids are dispersion, which are a collection of some with the same or similar structure, and there are several particles to form a colloid, so when a substance of 1mol is generally formed, the number of colloids is less than 1mol. Colloids are mixtures.

2. According to the different states of dispersants, it is divided into:

Aerosol: A dispersion system that uses gas as a dispersion medium. The dispersed phase can be gaseous, liquid or solid. Such as smoke diffusing in the air.

Liquid: A dispersion system that uses a liquid as a dispersion medium. The dispersed phase can be gaseous, liquid, or solid. Such as Fe(OH)3 glue.

Wide Slip Solid Sol: A dispersion system that uses solids as the dispersion medium. The dispersed phase can be gaseous, liquid or solid. Such as tinted glass, smoky quartz.

3. The intermolecular radius of smoke is 1-100nm, and the Tyndall effect can occur, so it is colloidal.
