Question

Write any one precaution you took while preparing semi per meable membrane using egg?​

Answer 1

A precaution that is taken while preparing semi-permeable membrane using egg is to ensure that the waterproof shell of the egg is removed with care.

* This is used in an experiment to study the process of osmosis.

* The remnants of egg shell affects the experiment and hence should be dissolved carefully using dilute acid.

* Also, it is to be ensured that the membrane is tightly attached to the funnel and no leakage should be present.

Answer 2

The primary precaution that I took while preparing a semi-permeable membrane using egg is using clean utensils and using the clean syringe.  

Explanation:

• In a basic science experiment using a dilute hydrochloric acid solution and water and some utensils, a semi-permeable membrane can be prepared with the help of a raw egg.
• This type of membrane is such where some elements can pass through it in the process of an osmosis but not all.
• The apertures present in the membrane are small and that only allows the passage of liquid but prohibits the solids from passing.
