氯酸铅是一种无机化合物,化学式为Pb(ClO3)2。它是白色发亮的鳞状物,在空气中变暗而不透明。氯酸铅存在无水物和一水合物。

制备

[编辑]

氯酸铅由一氧化铅碳酸铅氯酸水溶液反应得到:[1]

PbO + 2 HClO3 → Pb(ClO3)2 + H2O
PbCO3 + 2 HClO3 → Pb(ClO3)2 + H2O + CO2

物理性质

[编辑]

氯酸铅易溶于水,易潮解,也易溶于醇。[2]

化学性质

[编辑]

氯酸铅加热至230℃时分解并爆炸:[2][1]

Pb(ClO3)2 → PbCl2 + 3 O2
2 Pb(ClO3)2 → 2 PbO + 2Cl2↑ + 5 O2
