The following article will guide you about how to calculate pH of a solution. Also learn about the physiological importance of maintaining pH. pH: The pH of a solution is defined as the negative logarithm (base 10) of the hydrogen-ion concentration, i.e., pH = -log [H+] or pH = log (1/[H+]). Calculation of pH: For calculation of pH, [H+] ion [...]
In this article we will discuss about:- 1. Properties of Colloids 2. Separation of Colloids 3. Examples. Properties of Colloids: Some of the properties of colloids are as follows: i. Brownian Movement: Due to the impact of the solvent molecules, the colloid particles are continuously moving about. ii. Faraday-Tyndall Phenomenon (Optical Phenomenon): When a beam of light is passed through [...]
To understand the difference between a crystalloidal and a colloidal solution, one should remember that the forces which keep the solute particles in solution are roughly as follows: (a) Inherent movement of the solute particles, i.e., their diffusibility. (b) Inherent movement of the solvent molecules which continuously dash against the solute particles and thus help to keep them in solution. [...]
