liquid. ​

Answer 1

AnswEr :-

1. True

⇒ In the process of Sedimentation, the mixture is left undisturbed for a period of time. Then, the solid particles, which is insoluble, settle and form a layer.

⇒ In the process of Decantation, the liquid, called the supernatant, is poured in another container and the solid particles are left behind.

⇒ Since the solid particles are insoluble, sedimentation is possible.

⇒ Thus, the above statement is true.
