Colloids and solutions scatter light

The scattering of light by colloids is called _____.

A group of atoms that are held together by chemical forces, it is also the smallest unit of matter that can exist by itself and retain all of a substance's chemical properties.

Which one is not a colloid

What is a type of mixture that doesn't separate on its own but still contains undissolved particles

A stable mixture of two or more liquids e.g. icecream

A substance that can be added to an emulsion to keep the liquids completely mixed

Which of the following statements are true for pure substances? Select any 2 options.

It is a type of colloid made out of very small solid particles in a continuous liquid medium. These are quite stable and show the Tyndall effect. One example of this is paint.

It is a type of colloid in which the liquid medium has become viscous enough to behave more or less as a solid. An example of this is gummy candy

A type of Colloid that is a suspension of fine solid particles or liquid droplets in air or another gas. Aerosols can be natural or anthropogenic. An example of this is smoke.

A type of colloid formed by combining two liquids that normally don't mix. An example of this is mayonaise.

A colloidal system in which the particles are gas bubbles and the medium is a liquid. The term also is applied to material in a lightweight cellular spongy or rigid form. An example of this is Whipped cream.

It is a homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. ________________________ include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.

An easy way to determine whether a mixture is a colloid or not is through _________________________.

___________________ refers to substance that spreads particles where the particles are.

_________________ means to distribute or spread even over an area.

Colloid is with us in our daily life and it is important.

Also Called Physical manipulation or manual separation

Use filter like mesh cloth or filter paper to separate solid components from the liquid

Metals are attracted to magnets. A good way to separate metals with non metals

Used in separating soluble solid from liquid by the use of heat

This is the oldest method of salt production. It has been used since salt crystals were first noticed in trapped pools of sea water.

One of the approaches taken to isolate the gold from the soil was called _______.

In this method, small particles are aggregated to form colloidal size particles.

A ____________________ reaction is a reaction in which the positive ions and negative ions in two compounds switch partners to form two new compounds.

______________________is a chemical reaction that involves the gaining of electrons by one of the atoms involved in the reaction between two chemicals.

____________________ is any chemical reaction that involves the moving of electrons. When iron reacts with oxygen it forms a chemical because it has been oxidized

When iron reacts with oxygen it forms a chemical called _________________ because it has been oxidized (the iron has lost some electrons) and the oxygen has been reduced (the oxygen has gained some electrons).

An emulsion is a special type of mixture made by combining two liquids that normally don't mix.

Colloid consists of two parts: colloidal particles and the dispersing medium.

It is also a colloidal system which mainly consists of charged particles of carbon depressed in air.

Clouds are also colloidal system. In clouds,

water vapors are present in mixture with the dust particles. The water molecules present in cloud have electric charge on them and are of colloidal size.

It is the process of treating the skins of animals to obtain the leather. Skin of

animals is also a colloidal system in which the

colloidal particles are positively charged.

Extensive deposits of sand and clay

formed at the mouth of any river in sea

at the site where the river falls into sea

are called _______________. As it is very expected, the river water contains colloidal particles of sand and clay.

These are used to hide something by a

layer of it. In general, it is used to hide the

movement of troops. These are also colloidal

system in which the particles of titanium oxide are

dispersed in air.

The blue color of sky is due to

scattering of the blue color of sun

light by the colloidal particles of dust

dispersed in the air present in

atmosphere.

solution is a colloidal system and it removes the oil

and dirt by forming water soluble emulsions.

This involves using a strainer or a big screen to separate the components of solid mixtures.

What method of separating mixtures is shown in the picture?

This method is used to separate metals from non metals.
