Is a smoke a colloid?
No, smoke is not a colloid. A colloid is a mixture where one substance is dispersed in another, forming a stable suspension. Smoke is actually a suspension of solid particles in a gas.
Is yoghurt a colloid or solution?
Yogurt is classified as a colloid. It consists of milk proteins and fat dispersed in a liquid phase, forming a gel-like structure that gives it a creamy texture. In a colloid, the dispersed particles are larger than those in a solution but too small to settle out, which is characteristic of yogurt.
What kind of mixture is gelatin classified as?
Gelatin is classified as a colloid mixture, specifically a type called a gel. It consists of protein molecules dispersed within water, forming a semi-solid structure.
What agent keeps particles in a collid mixed?
A stabilizing agent, such as a surfactant or polymer, is commonly used to prevent particles in a colloid from agglomerating or settling out. These agents help to maintain the dispersion stability of the colloid by forming a protective barrier around the particles, preventing them from coming into close contact with each other.
How do solutions and colloidal dispersions compare in particle dispersion?
In colloids, the dispersed substance is not dissolved, but exists in small microscopic packets usually homogeneously dispersed through the medium. A fog, which is small water droplets suspended and evenly dispersed in air, is a colloid A solution contains a solute dissolved in a solvent, in which each individual molecule is discretely separate from all others in a solvent. The solute will usually ionise to multiple constituent parts. e.g. NaCl in water forming Na+ and Cl-. The solvent may also coordinate around the solute, bonding to it via van der Waals forces.

Is glue a colloid?
Yes, glue is a colloid. Colloids are mixtures where one substance is dispersed in another, forming a homogeneous solution. In the case of glue, the adhesive substance is dispersed in a liquid solvent to create a colloid.
Is gelatin a solution colloid or suspension?
Gelatin is a colloid. It consists of protein molecules dispersed throughout a liquid medium, forming a stable mixture.
Is mixture of chalk and water is a colloid?
No, a mixture of chalk and water is not a colloid. A colloid is a mixture where one substance is evenly dispersed in another substance, forming a homogeneous mixture. Since chalk does not form a homogeneous mixture with water, it is not considered a colloid.
IS AN ALLOY IS A SOLUTION COLLOIDS OR SUSPENSION?
An alloy is a solid solution composed of two or more metals. It is not a colloid or suspension as it does not have separate phases like in colloids or suspensions where particles are dispersed in a medium. In an alloy, the atoms of different metals are mixed at the atomic level, forming a homogeneous mixture.
Is hairspray a colloid?
Yes, hairspray is a colloid. It is a mixture of liquid droplets (such as water and various solvents) dispersed in air, forming a stable homogenous solution.
Is cordial in water a suspension or colloid?
Solution actually. Cordial is itself a solution, so adding water to it just changes concentration.

What is the difference between crystallization and precipitation?
Crystallization is the process of forming crystals from a solution, while precipitation is the formation of solid particles from a solution. In crystallization, the particles are arranged in a regular, repeating pattern, while in precipitation, the particles are randomly dispersed.
