Answer:

See explanation

Explanation:

All the substances in the mixture; sodium chloride ,lead II oxide and iron filings are solids.

The first step is to use a magnet to separate the iron fillings which is a magnetizable material.

The remaining part of the mixture is now dissolved in water. Lead II oxide is insoluble in water while sodium chloride is very soluble in water hence a filtrate and a residue are obtained.

The residue is lead II oxide which can be dried to recover the solid. The filtrate contains sodium chloride which is recovered by evaporating the solution to dryness.
