Worksheet based on Properties of colloids
Some of the properties of colloids are as follows: 1. A colloid is a hetrogenous solution but it appears to be homogenous solution. 2. Most of the particles of colloids cannot be seen even through microscope. 3. Colloids can’t be seperated by the process of filtration because colloid can pass through filter paper. 4. A colloid scatters a beam of light when passing through it because it’s particle are fairly large. And this process is known as Tyndal effect. Here, you can find some questions related to “Properties of...

The mixture of two or more liquids, which are normally immiscible, is known as Emulsion. Sometimes colloid and emulsion are used interchangeably. Emulsion contains both dispersed and continuous phase and the boundary between these two phases is known as Interface. In this article you can find questions related to “Emulsion” and their answers: Questions: 1. Cod liver is an example of: (a) Oil emulsion (b) Oil in water emulsion (c) Water in oil emulsion (d) Water in water emulsion 2.Milk is an example...

Colloidal solution are prepared from various methods so, they are not pure. So, colloidal solution should be purified before using it. Techniques used for purification of colloids are: 1. Dialysis Techniques 2. Ultra-filtration techniques Here, you can find some questions related to “Purification of Colloids” and their answers: Questions: 1. The process of separating a crystalloid, from a colloid by filtration, is called (a) Emulsification (b) Dialysis (c) Coagulation (d) Peptization 2. The separation of...

Colloids are mixtures in which a substance is divided into minute particles and dispersed throughout a second substance. This mixture is also called colloidal system, colloidal solution ar colloidal dispersion. There are two ways for preparing colloids. They are: 1. Preparing Colloids by Dispersion Method 2. Preparing colloids by Condensation of molecules from true solution In this article you can find some question related on “Preparation of colloids” and their answers: Questions: 1. Colloidal solution of arsenious sulphide is...

The rate of change of chemical reaction due to the presence of catalyst is known as catalysis. Catalyst can also participate on multiple chemical transformation. Catalysts that increase the rate of reaction is known as positive catalysts and those catalysts which decrease the rate of reaction is known as negative cataiysts. Here, you can find some questions related to ” Catalysts” and their answers: Questions: 1. The ability of a catalyst to accelerate the chemical reaction is known as: (a) selectivity (b) ...

Adhesion of atoms, ions, biomolecules or molecules of a gas, liquid or dissolved solid to a surface is known as Adsorption. Adsorption is a consequence of surface energy, similar to surface stension. Adsorptions are present in many natural physical, chemical and biological system and mostly used in industrial applications. Here, you can find some questions related to “Adsorption” and their answers: Questions: 1. Adsorption is a phenomenon, in which a substance: (a) Goes into the body of some other substance (b) Acumulates...
