OSMOSIS

What is Osmosis? Hello viewers, we are going to look at osmosis, the procedure, requirements and it's observations.  It is very important to know how to write an experiment on physics, chemistry and biology.  In your text book it is written in instruction format, which you can not write in your laboratory note book or in your examination.  You have got to write in Past Tense and Passive voice.  Lets go through the definition first. Definition: The movement of solvent molecules of a substance (solid, liquid and gas) from a region of lower concentration to the region of higher concentration through semipermeable membrane.   Aim of experiment:  To demonstrate the process of osmosis   Requirements: Concentrated sugar solution, distilled water, thistle funnel, parchment paper, thread, beaker, clamp stand   Procedure: A thistle funnel was taken.  The mouth of the thistle funnel was covered with a parchment paper and was tied properly.  In a beaker some distilled water was poured.  Concentrated sugar solution was...

Experiment On Diffusion

DIFFUSION Hi viewers:  It is very important to know how to write an experiment on physics, chemistry and biology.  In your text book it is written in instruction format, which you can not write in your laboratory note book or in your examination.  You have got to write in Past Tense and Passive voice.  A specimen is shown in the following, - Experiment on Diffusion.   Definition The movement of molecules of a substance (solid, gas and liquid) from a region of higher concentration to a region of lower concentration is called diffusion. 1. Aim of the experiment To demonstrate the process of diffusion 2. Requirements Beaker, water, Copper sulfate crystal 3. Procedure At first some water was taken in a beaker. A small piece of copper sulphate crystal was placed in a beaker. The beaker was kept undisturbed for some time. 4. Observation Copper sulphate crystal, which was placed in the beaker started to go into solution. The water around the crystal turns deep blue. Slowly, the molecules of...
