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 [...]
The below mentioned article includes a list of four simple experiments on osmosis. 1. Experiment to demonstrate the osmosis by using sheet of cellophane or goat bladder: Requirements: Beaker, thistle funnel, goat bladder or sheet of cellophane, thread, water and sugar solution. Method: 1. Cover the lower opening of the glass tube with the goat bladder or sheet of cellophane [...]
In this article we will discuss about the process of osmosis in plants. It is usually seen, that when two liquids of different densities are separated from each other by placing a membrane between them, by which the water of the liquid of lower density flows towards the liquid of higher density, then such separating membrane is called the semipermeable [...]
