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 [...]
Osmotic pressure can be measured in various ways which are described below:- 1. Mechanical Methods 2. Biological Methods 3. Physical Methods. 1. Mechanical Methods: (i) By Putting Weights: The simplest way is to apply adequate pressure (i.e., weight) upon the stronger solution to prevent any rise of volume. That pressure which is just needed to stop the increase of volume [...]
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 [...]
