Which of the following is a heterogenous mixture?
Sand and Iron fillings
A heterogeneous mixture does not have the same composition throughout, and its components can be seen and separated physically.
In a mixture of sand and iron filings, the particles stay separate and visible, and a magnet can pull the iron out. Salt solution, vinegar and air are all uniform throughout, so they are homogeneous mixtures.
Hence, the answer is Sand and Iron fillings.
