Question

a mixture of sawdust and water can be separated by magnetic separation true or false
if false the correct the wrong statement​

Answer 1

Sedimentation and decantation is the process of separation of solid that is heavier than liquid by pouring out the liquid after the solid is 'settled at the bottom' of the vessel.

The sawdust is no't heavier than liquid so it doesn’t fall to the bottom of vessel in the mixture, hence cannot be separated by sedimentation and decantation. Instead we can use the evaporation technique to separate the sawdust from water.
