Hint: To distinguish between a pair of compounds, find out a suitable reagent that forms a precipitate with one of the compounds, but the same reagent should not form a precipitate with another compound. If the reagent forms precipitate with both compounds, then one of the precipitate should be soluble in the excess of the reagent, whereas other precipitate …

Lead is soft and malleable and has a relatively low melting point. Zinc is a chemical element with the symbol Zn and atomic number 30. It is a brittle transition metal at room temperature but malleable at higher temperatures. Zinc is also known for its anti-corrosive properties. Lead has been used throughout history for a variety of purposes.
