Question

1 Why separation is important ?
2. Differenciale between sedimentaion and decantation?​

Answer 1

Answer:

1. Hence, we need to separate both from each other. Thus, separation of substances is necessary to obtain pure substances for domestic purposes, industrial purposes and research work. Even the example used earlier of gases present in air is also an example of obtaining pure substances.

2.The key difference between sedimentation and decantation is that the sedimentation allows the separation of two substances via settling of one substance whereas the decantation allows the separation of two substances via pouring off one substance. Both sedimentation and decantation are important separation methods
