Question

differentiate between wool, cotton and silk by an experiment​

Answer 1

Answer:

Distinguish between artificial silk and natural silk.

1. Take a piece of natural silk fabric and another piece of artificial silk fabric.

2. Burn both the fabrics separately and observe the smell produced.

Conclusion:

1. The fabric which burns giving a smell of burning hair will be natural silk or pure silk.

2. The fabric which burns giving a smell of burning paper will be artificial silk.

Just like silk, wool is also made up of proteins. So, a piece of woollen fabric also burns giving the smell of burning hair.
