A colloid is a heterogeneous mixture and quite stable So, statement 1 is not correct.
The size of particles of a colloid is too small to be individually seen by naked eyes. So, statement 2 is not correct.
Colloids are big enough to scatter a beam of light passing through thern and rnake their path visible. So, statement 3 is correct.
Common examples of colloids are-
So, statement 4 is correct.
Therefore, the correct answer is (c).

Consider the following statements regarding the properties of a colloi...
The correct answer is option 'C' - Statements 3 and 4 only are correct.
Explanation:
1. It is a heterogeneous mixture and is unstable: This statement is incorrect. A colloid is actually a homogeneous mixture, not a heterogeneous one. In a colloid, the particles are evenly distributed throughout the mixture. Additionally, colloid is a stable system because the dispersed particles do not settle down easily due to the presence of a stabilizing agent called the dispersion medium.
2. The size of particles of a colloid is large and can be seen by naked eyes: This statement is incorrect. The size of particles in a colloid is actually very small, typically in the range of 1-1000 nanometers. These particles are not visible to the naked eye and require the use of a microscope or other instruments to be observed.
3. These are big enough to scatter a beam of light passing through it and make its path visible: This statement is correct. The particles in a colloid are large enough to scatter light, a phenomenon known as the Tyndall effect. When a beam of light passes through a colloid, the particles scatter the light in all directions, making the path of light visible. This effect is commonly observed in fog, clouds, mist, and other colloidal systems.
4. Fog, clouds, mist, and colored gemstone are some of the examples of colloid: This statement is correct. Fog, clouds, mist, and colored gemstones are all examples of colloids. Fog and mist are colloidal suspensions of water droplets in air, while clouds are colloidal suspensions of water droplets or ice crystals in the atmosphere. Colored gemstones like opal and ruby also exhibit colloidal properties, where tiny particles of a different material are dispersed within the gemstone, giving it its characteristic color.
In summary, only statements 3 and 4 are correct. A colloid is a homogeneous mixture, not a heterogeneous one, and its particles are too small to be seen by the naked eye. However, they are large enough to scatter light, which makes the path of light visible. Colloids can be found in various natural and synthetic systems, including fog, clouds, mist, and colored gemstones.
