Preparation of Lead dioxide: this chemical can be prepared by PbAC₂·3H₂O and AR concentrated solution of sodium carbonate. This reaction will need reagent Cl2.

Pb(CH₃COO)₂+2Na₂CO₃+Cl₂=PbO₂↓+2CH₃COONa+2NaCl+2CO_2↑

Uses of Lead dioxide: Lead dioxide is well known for being a good oxidizing agent with example reaction listed below:

2 MnSO₄ + 5 PbO₂ + 6 HNO₃ → 2 HMnO₄ + 2 PbSO₄↓ + 3 Pb(NO₃)₂ + 2 H₂O
2 Cr(OH)₃ + 10 KOH + 3 PbO₂↓ → 2 K₂CrO₄ + 3 K₂PbO₂ + 8 H₂O

When you are using this chemical, please be cautious about it as the following:
This chemical can react exothermically with other chemicals. This chemical that at low level will cause damage to health. It may present an immediate or delayed danger to one or more components of the environment. In addition, it is harmful by inhalation and if swallowed and harmful to aquatic organisms which may cause long-term adverse effects in the aquatic environment. In case of accident or if you feel unwell seek medical advice immediately (show the label where possible). This material and its container must be disposed of as hazardous waste.
