Properties of command IV oxide

Physical Properties:

The Molar mass of command oxide is 239.1988 g/mol

It shows up with dark-brown shade or in black color powder

Lead oxide has a thickness of 9.38 g/cm3

Its Melting suggest is 290 °C (554 °F; 563 K)

Solubility: the is insoluble in water and alcohol and also soluble in acetic acid

Chemical Properties:

Let,s inspect some that the command iv oxide chemistry reactions


When command dioxide is cook in air, the decomposes together follows:

24PbO2→ 2Pb12O19+ 5O2

Pb12O19→ Pb12O17+ O2

2Pb12O17→ 8Pb3O4+ O2

2Pb3O4→ 6PbO+ O2

Reaction through Acids and also Bases:

Lead dioxide (PbO2) is one amphoteric compound with prevalent acidic properties. Hydroxy plumbate ion, 2− is created when lead oxide is dissolved in strong base.

PbO2+ NaOH + 2 H2O → Na2

lead dioxide reaction with hot acids, due to the fact that Pb4+ cation is really instable, it converts in to secure Pb2+ state and oxygen is liberated.

2PbO2 + 2H2SO4 → 2PbSO4 + 2H2O + O2

2PbO2 + 4HNO3 → 2Pb(NO3)2 + 2H2O + O2

PbO2 + 4HCl → PbCl2 + 2H2O + Cl2

Oxidising Agent:

Lead dioxide is familiar for its solid oxidizing properties,

MnSO4 + 5 PbO2 + 6 HNO3 → 2 HMnO4 + PbSO4 + Pb (NO3)2 + 2 H2O

Cr (OH)3 + 10 KOH + 3 PbO2 → K2CrO4 + K2PbO2 + 8 H2O

Production of command IV oxide:

The reaction of Pb3O4 v nitric mountain produces the dioxide.

Pb3O4+ HNO3→ PbO2+ Pb (NO3)2+ H2O

Plumbic oxide is treated, once lead chloride is treated with sodium hypochlorite (NaClO).

Lead IV Oxide PbO2 Uses:

Lead dioxide is used in the to produce of matches, pyrotechnics, the curing the sulfide polymers and also dyes.

It is also used in the development of high-voltage lightning arresters

lead dioxide anodes were supplied for the production of glyoxylic acid from oxalic mountain in a sulfuric mountain electrolyte.

It is used as the cathode the lead acid batteries.

Key Points:

Lead (IV) oxide is an inorganic compound i m sorry is amphoteric in nature and has one oxidation state the +4. Command dioxide exist in two major polymorphs, they space alpha and beta, which occur naturally together rare mineral scrutinyite and plattnerite.
