1 Comment on Coagulation of Colloidal Solution

Science > Chemistry > Colloids > Coagulation of Colloidal Solution The process of precipitation of colloidal particles due to aggregation of the particles is called coagulation or flocculation. Explanation: The presence of the same type of electric charge on colloidal particles causes repulsion and keep them in a suspended state. If by some means, the […]

3 Comments on 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 […]

Electric Potential

Science > Physics > Electrostatics > Electric Potential Electric Potential at a Point: The electric potential at any point in the electric field is defined as the work that must be done by the external force to move unit positive charge from infinity to that point without acceleration. If W is the work done in […]

Science > Biology > Zoology > Histology > Epithelium or Epithelial Tissue In this article, we shall study about the epithelium or epithelial tissue. Higher-level organisms have multicellular structure. The cells differ from one another in their shape, size. Cells arise from pre-existing cells by the process of cell division. In multicellular organisms, cells are […]
