What difference does the charge on the anion have in the ability of the salt to coagulate the colloid?
The charge on the anion in the salt can affect the coagulation of a colloid by influencing the stability of the colloidal particles. Anions with higher charges can more effectively neutralize the positive charge on the colloidal particles, leading to stronger coagulation. Additionally, anions with multivalent charges may form stronger bonds with the colloidal particles, enhancing the coagulation process.
Why are ruby colloid?
Ruby is not a colloid; it is a crystalline form of aluminum oxide with traces of chromium that gives it a red color. Rubies are not formed as colloidal particles but rather as structured crystals within the Earth's crust.
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
What property do colloidal dispersions and solutions and other kinds of mixtures do not?
Colloidal dispersions have particles that are larger than individual molecules, but smaller than those in suspensions. Unlike solutions, colloidal dispersions do not display the property of Tyndall scattering, which is the scattering of light by particles in a colloid that distinguishes it from a true solution.
Is milk a solution or a colloid?
This depends: an ink may be a true sollution or a colloidal solution, or a suspension.
How can distinguish a colloid from a suspension?
the colloidal particle show tyndal effect while suspended particles donot. Colloidal particles donot settle down but the suspended particles get settledown.

How can you distinguish a colloid form?
A colloidal solution is not transparent, has some opalescence.
Will colloid particles eventually settle out?
They won't because a colloidal mixture is a perfect solution...
What happens if a colloid is passed through a filter?
When a colloid is passed through a filter, the larger particles of the colloidal suspension do not pass through the filter membrane, while the smaller solvent molecules can. This results in the separation of the colloidal particles from the dispersing medium. The filter retains the colloidal particles, leading to a clearer solution on the other side, which contains primarily the solvent and any small dissolved substances. Therefore, filtration effectively removes the colloidal particles from the mixture.
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.
Is soil a colloid?
Yes, soil can have colloidal properties because it contains organic matter, clay particles, and other materials that can form colloidal suspensions. Colloids are particles that are intermediate in size between true solutions and suspensions, and soil can exhibit colloidal behavior in terms of its ability to retain water and nutrients.
In a colloid the particles are?
Colloids have moderately sized particles. (small enough to stay in suspension)
What is the colloidal particles that spread throughout a suspension?
A homogeneous solution contain ions or molecules.A colloid contain insoluble particles in the range 1-1000 nm.
Colloid can be detected by using?
A colloid can be detected by using a light scattering technique called Tyndall effect. When a beam of light is shone through a colloid, the particles in the colloid scatter the light, making the beam visible. This is a simple way to visually confirm the presence of colloidal particles in a solution.
