PHASES OF COLLOIDS
(1) Phases of colloids : We know that a colloidal solution is of heterogeneous nature. It consists of two phases which are as follows:
(i) Internal phase or Dispersed phase (Discontinuous phase) : It is the component present in small proportion and is just like a solute in a solution. For example in the colloidal solution of silver in water (silver acts as a dispersed phase)
(ii) External phase or Dispersion medium (continuous phase) : It is generally component present in excess and is just like a solvent in a solution. For example, in the colloidal solution of silver in water. Water act as a dispersion medium.
What else can I help you with?
Why is halwa a colloid?
Halwa is considered a colloid because it is a mixture of two phases - a solid dispersed in a liquid. The sugar, ghee, and other solid ingredients are finely dispersed in water to form a gel-like consistency, creating a colloid.
How do you compare solutions suspension and colloidal suspension?
Homogeneous solutions have only one phase.A suspension or a colloid has two phases.
What is a colloidal salt?
1) A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium) in which the colloid is dispersed.2) A colloid is a substance microscopically dispersed evenly throughout another substance.
Is mayonnaise a colloid?
Mayonnaise is a colloid.yes, it is a colloid.
What are the two states of a colloid?
The two states of a colloid are either a gas or liquid and a solid. The dispersion medium is either the liquid or gas that is mixed with the dispersed medium, which are usually solid particles.
How can you distinguish a colloidal from a solution?
A colloid is a form of suspension in a liquid or gas, the two phases are distinct.
What property do colloid and suspensions have that a solución dónde nota have?
Unlike in a suspension, the particles in a colloid do not separate into two phases on standing.
What is the difference between a solution a colloid and suspension?
A solution has only one phase.A suspension has two phases.A colloid has two phases but the colloidal particles have dimensions under 1 micrometre.
What is the difference between a solution a suspension and a colloid?
A solution has only one phase.A suspension has two phases.A colloid has two phases but the colloidal particles have dimensions under 1 micrometre.
How many phases are present in colloid?
2 or more.

How do you compare solutions suspension and colloidal suspension?
Homogeneous solutions have only one phase.A suspension or a colloid has two phases.
Is milk a solution or a colloid?
This depends: an ink may be a true sollution or a colloidal solution, or a suspension.
What is a colloidal salt?
1) A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium) in which the colloid is dispersed.2) A colloid is a substance microscopically dispersed evenly throughout another substance.
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.
What are two good examples of a colloid?
A colloid is a mixture that appears to be a solution but it is actually a mechanical mixture. Two examples of a colloid are : MILK and STARCH DISSOLVED IN WATER.
Why colloidal solutions are called heterogeneous?
A colloid is a mixture where the size of the particles is less than the particles of suspension. These particles are uniformly spread out throught the solution. Due to relatively smaller size of particlesas compared to solution this appears to be homogenious.but a colloid solution is ahetrerogeneous mixture.The componenys of a colloid are in a dispersed phase in a medium.eg. milk
