But blood is also a colloidal solution, Blood is a colloid because in blood the blood cell size is between 1nm to 100nm. A mixture in which one substance is divided into minute particles (called colloidal particles) and dispersed throughout a second substance. Blood is a colloidal solution of an albuminoid substance.

Erythrocytes and platelets are large enough to form sedimentation and therefore enabling us to categorize blood as a suspension . However, when looking at blood from a solution perspective, we can say that it is composed of sugars, salts, urea, and proteins. Blood is, therefore, also a colloid of proteins.

A sol is a colloid made out of very small solid particles in a continuous liquid medium. Sols are quite stable and show the Tyndall effect. Examples include blood, pigmented ink, cell fluids, paint, antacids and mud.

Blood is a mixture that can be separated by a machine called a centrifuge into its two main parts: plasma and red blood cells. Mixtures can be liquids, gases, and solids.

Coffee is a solution, not a compound or mixture, as it includes a solute that dissolves into a solvent. Coffee can also be considered a mixture since it involves two mixed substances, but this is too vague.

There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures.

Classifying Matter Matter can be classified into several categories. Two broad categories are mixtures and pure substances. A pure substance has a constant composition. All specimens of a pure substance have exactly the same makeup and properties.

In chemistry, a mixture is a material made up of two or more different substances which are not chemically combined. A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.

Milk is a colloid, with tiny globs of butterfat suspended throughout the liquid. Whipped cream is a colloid too. Colloids typically don’t separate into their individual components over time.

11.7: Colloidal Suspensions

The particles making up a colloid are smaller than those in a suspension. If you put cream in a jar and shake for a about 10 minutes the fat molecules stick together, making butter and a liquid called buttermilk. Butter is also a colloid as there are water molecules trapped in between the fat.

A mixture with particles that can be easily seen and separated by being filtered or settling. If you try to put too much sugar into a cup of tea, it will not fully dissolve and will leave some sugar on the bottom of the cup, making the tea a Suspension.

A colloid is a solution in which the particle size ranges between 10-7 and 10-5 cm. For example, milk, blood, honey, smoke, ink, gum, starch solution etc. Saturated solutions have the maximum amount of solute dissolved in them. No more solute can be made to dissolve.

Cheeses and yogurts are complex colloidal suspensions made from animal’s milk. The colloidal suspension of milk can be described an oil in water emulsion, with insoluble proteins forming complicated micelles in a water solution.

Apple juice can be a heterogeneous mixture or a homogenous mixture. The fiber and other nutrients in the apple serve as the solute and the water is the solvent. If the apple juice has visible particles (fiber strands or powdery particles), then it is a heterogeneous mixture.

It is a suspension of solids in a liquid. Ketchup is a colloid, i.e. a substance that cannot be easliy placed into either the solid, liquid or gas categories. Ketchup is in fact a sol, which is solid particles suspended in liquid.

Answer : Milk of magnesia is a suspension as it is a heterogeneous mixture.

Soda is a solution. The main ingredient in soda is water. Sugar, flavoring, coloring, and carbon dioxide are dissolved in the water at low…

In summary: A solution is always transparent, light passes through with no scattering from solute particles which are molecule in size. The solution is homogeneous and does not settle out. A colloid is intermediate between a solution and a suspension. While a suspension will separate out a colloid will not.

Examples of suspensions include oil and water, dust or soot in air, sand and water and muddy water.

Milk is not a solution because it has more than one phase suspended in it — it has a liquid phase and a solid phase. Unhomogenized milk is not a solution, it’s a suspension because the fat (aka cream) will separate from the rest of the milk and rise to the top, since fat is less dense than water.

NCERT textbook says that milk of magnesia [chemically Mg(OH)₂] is an example for colloid. It is a solid-in-liquid type colloid, which makes it under the category Sol.

Milk is an emulsified colloid of liquid butterfat globules dispersed within a water-based solution.

Salt water is a true solution and is not a colloid. It is a true solution since salt particles completely dissolve in water.

The most abundant particle in a colloid is Dispersing Phases.

Colloids are common in everyday life. Some examples include whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper. Every colloid consists of two parts: colloidal particles and the dispersing medium.

hydrocolloid

Examples of Colloids

Smoke is an example of a colloidal system where dispersed Phase is Solid and dispersion Medium is Gas, which is the correct answer and the option which matches is C.

colloid. [ kŏl′oid′ ] A mixture in which very small particles of one substance are distributed evenly throughout another substance. The particles are generally larger than those in a solution, and smaller than those in a suspension. Paints, milk, and fog are colloids.
