Question

Hydrogen peroxide reacts with which of the following compounds to form yellow precipitate of litharge?
A. $ PbO $
B. $ Pb{O_2} $
C. $ A{g_2} $
D. $ Ag $

Answer 1

Hint: Litharge is a natural mineral form of $ lead\left( {II} \right) $ oxide, often known as $ PbO $ . Litharge is a secondary mineral that forms when galena ores oxidise. It takes the form of coatings and encrustations with a tetragonal crystal structure on the inside. It has the orthorhombic form massicot and is dimorphic with it.

Complete answer:
The inorganic compound $ lead\left( {II} \right) $ oxide, often known as lead monoxide, has the chemical formula $ PbO $ Litharge, which has a tetragonal crystal structure, and massicot, which has an orthorhombic crystal structure, are two polymorphs of $ PbO $ . $ PbO $ is used primarily in lead-based industrial glass and industrial ceramics, as well as computer components. It's a type of amphoteric oxide.
Litharge is a natural mineral form of lead(II) oxide, often known as $ PbO $ . When $ {H_2}{O_2} $ interacts with lead dioxide, it produces lead dioxide. The following are the reactions:
 $ {H_2}{O_2} + Pb{O_2} \Rightarrow PbO + {H_2}O $
 $ 3Pb{O_2} + 2{H_2}{O_2} \to P{b_3}{O_4} + 2{O_2} + 2{H_2}O $
So, the correct option is: (B) $ Pb{O_2} $ .

Additional Information:
Litharge’s oxidising and reducing abilities are limited. However, redox reactions can still happen. The majority of chemicals in this class are water insoluble or only slightly soluble. If the solution is soluble in water, it is usually neither strongly acidic nor strongly basic. These chemicals do not react with water. When aluminium carbide is heated with lead oxide, it oxidises with incandescence. Lead oxide and aluminium powder mixtures (as well as other metals such as sodium and zirconium) cause explosive explosions.

Note:
Chrome-yellow and chrome-green pigments are made with litharge as a main component. It's used as a rubber accelerator, toughener, and control ingredient, as well as a catalyst in oil refinement, where it breaks apart some of the organic sulphur compounds found in crude oil.
