Pb(OH)₂ is a base and can react with acids to form salts and water.

3. Common chemical equations involving Pb(OH)₂:

Acid reaction: Pb(OH)₂ + 2HNO₃ → Pb(NO₃)₂ + 2H₂O.

Reaction with salt: Pb(OH)₂ + 2NaCl → PbCl₂ + 2NaOH.

4. Synthesis of Pb(OH)₂

4.1 Laboratory synthesis of Pb(OH)₂:
Pb(NO₃)₂ + 2NaOH → Pb(OH)₂↓+ 2NaNO₃.
PbCl₂ + 2NaOH → Pb(OH)₂ + 2NaCl.

4.2 Industrial synthesis of Pb(OH)₂:
In industry, Pb(OH)₂ is typically synthesized from PbO and water.
PbO + H� -> ��O → Pb(OH)₂.
Additionally, it can also be synthesized from lead and water during electrolysis.
