Applications of Colloids

Science > Chemistry > Colloids > Applications of Colloids Natural Applications of Colloids: Blue Colour of Sky: When the light is incident on particles whose size is smaller than the wavelength of light, it is scattered. The blue colour of the sky is due to the scattering of light by small particles (dust particles along […]

Electrical Properties of Colloids

Science > Chemistry > Colloids > Charge on Colloidal Particles The colloidal particles carry an electric charge. The most important property of colloidal solution is that all suspended particles possess either positive or a negative charge. i.e. they carry the same nature of the charge. The mutual forces of repulsion between similarly charged particles prevent […]

Properties of Colloids

Science > Chemistry > Colloids > Properties of Colloids In this article, we shall study the general, mechanical and optical properties of colloids. General Properties of Colloids: Heterogenous Character: The ultramicroscopic examination indicates that colloidal dispersion is a heterogeneous system consisting of a continuous dispersion medium and discontinuous disperse phase. Visibility: Colloidal particles cannot be seen […]
