Oxides of Group 4 Elements

In the case of lead(IV) oxide, the reaction requires ice-cold hydrochloric acid. If the reaction is carried out at warmer temperatures, the lead(IV) chloride decomposes to give lead(II) chloride and chlorine gas. This is because the preferred oxidation state of lead is +2 rather than +4.

Can you turn lead dioxide into lead?

Sci. Technol. 2010, 44 (23), 8950–8956. DOI: 10.1021/es102318z. Lead dioxide can be heated to 600 °C and it will thermally decompose into PbO and O 2. This likely creates lead fumes but this may be one way to accomplish the task. Optionally, you could dissolve the lead dioxide in acid then reduce it from a salt.

Lead Oxide

Lead oxide can occur as a transition form in oxidation/reduction process of the PbO2 /Pb (II) couple. It is particularly stable in alkaline solutions. Anodic oxidation of Pb results in the growth of β -PbO, which can then be transformed to α -PbO. The structure of PbO deposit depends on hydroxide (NaOH) concentration.
