Colloids contain larger particles that do not readily settle and are used to increase intravascular volume, while crystalloids contain smaller particles that can freely pass through the capillary membrane and are used to maintain fluid balance. Colloids are often more expensive and can carry a risk of adverse reactions, such as anaphylaxis, compared to crystalloids.

Homogeneous mixture of particles so small they cannot be seen and will never settle?
The substance you are describing is a colloid. Colloids contain particles that are intermediate in size between a solution and a suspension. These particles are small enough to stay dispersed and stable throughout the mixture, giving it a uniform appearance.
How can you tell the difference between suspension colloid or solution?
A suspension is a heterogenous mixture where particles settle out, a colloid is a homogenous mixture where particles are evenly dispersed but do not settle, and a solution is a homogenous mixture where solute is dissolved in a solvent. You can distinguish between them by observing if the mixture is uniform throughout (solution), if it has visible particles that settle over time (suspension), or if it appears uniform but scatters light (colloid).
Is candle a colloid If yes what type of colloid is it?
No it is not a colloid. Colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspension.
Is mouthwash a colloid?
Yes, mouthwash is a colloid. It is a liquid mixture containing suspended particles that do not settle out.
Is gold a colloid?
No, gold is not a colloid. Gold is a pure element and does not form a colloid by dispersing into another substance.
Is gelofusin a colloid or crystalloid?
Gelofusin is a colloid solution. It contains natural polysaccharides derived from starch and is used for volume replacement and maintenance of blood pressure in patients with hypovolemia.
What is colloid mean?
Resembling glue or jelly; characterized by a jellylike appearance; gelatinous; as, colloid tumors., A substance (as albumin, gum, Gelatin, etc.) which is of a gelatinous rather than a crystalline nature, and which diffuses itself through animal membranes or vegetable parchment more slowly than crystalloids do; -- opposed to crystalloid., A gelatinous substance found in colloid degeneration and colloid cancer.

What is the difference between colloid solution to colloid mixture?
A colloid solution refers to a homogeneous mixture where one substance is finely dispersed throughout another substance, such as in colloidal suspensions like milk. A colloid mixture, on the other hand, refers to a collection of different colloids mixed together, each retaining its individual properties.
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 hemodilution?
Hemodilution is a technique in which whole blood from the patient is withdrawn before surgery for temporary storage and replaced with crystalloid or colloid solutions that restore the normal fluid volume of the blood without adding new blood cells.
Why there is oncotic pressure difference between atrtereoles and venules?
Oncotic pressure is the pressure exerted by colloid particles. As colloid particles do NOT leave the blood vessels oncotic pressure is SAME in arteriole and venules.
How can you tell the difference between a solution and a colloid?
a colloid contains larger particles than a solution. the particles are still too small to be seen easily, but are large enough to scatter a light beam

What is one difference between a colloid and solution?
One difference is the size of particles: in a solution, particles are uniformly dispersed at a molecular level, whereas in a colloid, particles are larger and dispersed throughout the mixture but do not settle out.
Is dextrose a crystalloid substance?
Yes, dextrose is a crystalloid substance. It is a type of sugar that can be dissolved in a solution, making it a source of carbohydrates for the body when administered intravenously.
