GCSE Chemistry Question Analyses Topic: Chemistry - Short Questions

Exam Questions:

1) What happens when persistent dialysis of a colloidal solution is carried out?

2) What is a biodegradable polymer?

3) Define the following with an example of denatured protein.

Answer:

For GCSE Chemistry, you should know:

1) A small amount of the electrolyte is what gives a colloidal sol its stability. The electrolyte is entirely eliminated during prolonged dialysis. The liquid sol consequently coagulates and loses stability.

2) Biodegradable polymer is a type of polymer that breaks down naturally, such as through bacterial activity.
It aids in the
reduction of natural pollution. Synthetic polymers cannot biodegrade, whereas natural polymers can. Paper, wool, wood, and other biodegradable items are just a few.

3) Denatured protein is precipitated protein that has been heated with alcohol, concentrated inorganic acids, or heavy metal ions to cause irreversible precipitation. When a protein is uncoiled, its shape and distinctive biological function are lost. The egg white congeals during cooking. Another illustration of protein denaturation is the transformation of milk into curd. Cooking meats is also a form of denaturing proteins.

Work hard for your GCSE Chemistry examination!
