Dross - Wikipedia

Dross is a mass of solid impurities floating on a molten metal or dispersed in the metal, such as in wrought iron. It forms on the surface of low-melting-point metals such as tin, lead, zinc or aluminium or alloys by oxidation of the metal.For higher melting point metals such as steel, oxidized impurities melt and float making them easy to pour off.

Give chemical test to distinguish between lead nitrate ...

Lead nitrate and zinc nitrate can be distinguished by adding dil. sulphuric acid to both. Explanation - - When dil. H2SO4 is added to lead nitrate, double precipitation reaction occurs giving white ppt of lead sulphate. Pb(NO3)2 + H2SO4 → PbSO4 (white ppt) + 2HNO3 - When dil. H2SO4 is added to zinc nitrate, no change is observed.
