Amphoteric oxide of lead

Answers

GPT-4o mini
The amphoteric oxide of lead is lead(II) oxide, which is commonly represented as \( \text{PbO} \). Amphoteric oxides can react with both acids and bases.

In acidic conditions, lead(II) oxide can react with acids to form lead salts. For example, when it reacts with hydrochloric acid (\( \text{HCl} \)), it forms lead(II) chloride (\( \text{PbCl}_2 \)):

\[
\text{PbO} + 2 \text{HCl} \rightarrow \text{PbCl}_2 + \text{H}_2\text{O}
\]

In basic conditions, lead(II) oxide can react with bases to form plumbates. For example, when it reacts with sodium hydroxide (\( \text{NaOH} \)), it can form sodium plumbate (\( \text{Na}_2\text{Pb(OH)}_4 \)):

\[
\text{PbO} + 2 \text{NaOH} + 2 \text{H}_2\text{O} \rightarrow \text{Na}_2\text{Pb(OH)}_4
\]

Thus, lead(II) oxide demonstrates its amphoteric nature by participating in reactions with both acids and bases.
