Vedclass · Answer

(B) White lead is a basic lead carbonate,chemically represented as $2PbCO_3 \cdot Pb(OH)_2$.To prepare white lead,lead plates are exposed to the vapours of acetic acid $(CH_3COOH)$ in the presence of air and carbon dioxide.The acetic acid reacts with lead to form lead acetate,which subsequently reacts with carbon dioxide and water to produce white lead.Therefore,acetic acid is the essential reagent used in its preparation.
