In summary:

Muddy water is a suspension. If the muddy water is kept undisturbed for some time, the mud settles down. Suspension is a heterogeneous mixture of particles from which the particles settle with time.

Suspensions

1. 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.
2. A suspension is cloudy and heterogeneous.
3. A colloid is intermediate between a solution and a suspension.

11.7: Colloidal Suspensions

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.

Coffee is both a solution and a suspension: When in water, coffee beans contain many water soluble compounds that dissolve in the water. These are the color and flavor of coffee you want. This is a solution.

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.

Answer and Explanation: 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.

Milk of magnesia is a suspension of Mg(OH)2 in water. Milk of Magnesia is called as magnesiu hydroxide.

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

Blood has the characteristic of both a colloid and a suspension making it a colloidal suspension. In its normal stable state, blood is a suspension, which is a colloid. It mainly consists of red & white blood cells, and lymphocytes suspended in plasma.

Milk is a colloid, with tiny globs of butterfat suspended throughout the liquid. Whipped cream is a colloid too.

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. The process of settling of colloidal particles is called coagulation or precipitation of the sol.

Blood is colloidal and has solid cells suspended in liquid blood plasma. In hospitals, the cells are separated from the plasma and they can be remixed, so blood is a lyophilic colloid.

Particles of colloidal solution are called colloid. Colloids are dispersed throughout the solvent. Milk, ink, blood, solution of soap or detergent, etc. are some common examples of colloidal solution.

Examples of Colloids

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 solution cannot be filtered but can be separated using the process of distillation. A suspension is cloudy and heterogeneous.

Thus, blood is a negatively charged sol. Thus, the correct option is (C) negatively. Additional Information: The colloidal particles possess an electrical charge. Note: Haemoglobin in blood is positively charged.

A sol is a colloidal solution and suspension of very small solid particles in a continuous liquid medium. It is quite stable and show the tyndall effect. Example:- milk, blood, pigment ink, cell fluids, paint, clouds,shaving cream etc.

Sols are classified on the basis of size of solid particles present in it. Explanation: When solid particles that are very small in size are present in a continuous liquid medium then the solution formed is known as sol. For example, blood, cell fluid, milk of magnesia etc are all sols.

A colloidal solution in which liquid particles are dispersed in a liquid medium is known as emulsion. Thus, in an emulsion, dispersed particles and the dispersion medium both are in liquid phase. Milk is an emulsion in which fat globules are suspended in water. Casein is a lyophilic (solvent loving) sol.

Classification in terms of the physical state: (i) Solid solution/solid sol: Both the dispersed phase and the dispersion medium are solid. Gemstones are solid sols.

Solution is clear, particle size is less than 1 nm, solute is completely soluble in solvent. Particles insoluble in solvent. Large paticle size. Sol is a type of colloid inn which dispersed phase is solid and dispersion media is liquid.

Black diamonds, vision glasses, photochromatic glasses and ruby stone are examples of solid soils. Hence, all the four options A ), B ), C ) and D) are correct answers. Note: Alloys, coloured glasses and gemstones are usual examples of solid sol.

Answer. Butter is an example of a colloidal solution and it is occasionally find out best ideas of it and it is mixture of the substance which gets suspended in the part of the fluid. This process will found in the part of the fluid and colloidal systems has three states such solid , gas and liquid .

Yes, Bread is an example of solid foam since it is formed by baking mixture of flour and salt, yeast and water.

Gels is that kind of colloid in which the dispersed phase is a liquid and the dispersion medium is a solid. Butter is a dairy product containing up to 80% butterfat (in commercial products) which is solid when chilled and at room temperature. So it’s clear that butter is a Gel not an Emulsion.
