Question

describe the steps you would follow to separate a mixture of silt,potassium and nitrate(soluble in water)find coal dust.​

Answer 1

HERE IS YOUR ANSWER.

Dissolve the mixture in water. As potassium nitrate is soluble in water, it will dissolve in water, leaving behind silt and fine coal dust. Silt being heavier will settle at the bottom and coal dust being fine will rise to the surface and float on the surface of water. ... On evaporation we will get potassium nitrate.
