名　称：过硫酸钠
分子式：Na2S2O8
分子量：238.13
性状:
过硫酸钠是一种白色、无味晶体，常作强氧化剂使用，也可用作单体聚合引发剂。它几乎不吸潮，由于能达很高的纯度而具有特别好的稳定性，便于储存。另外，它还具有使用方便、安全等优点。

过硫酸钠属于非易燃品，但由于能释放氧而有助燃作用，因此必须在一定条件下储存。首先必须存放在干燥、密闭的容器中，其次应避免阳光直射、热源、潮湿等不利因素。另外，一些杂质如脏物、铁锈、少量金属以及还原剂可能引起过硫酸钠的分解，在存放和使用过程中也必须注意。由于潮湿的过硫酸钠粉末及其水溶液有漂白和轻微的腐蚀作用，因此使用过程中应避免眼睛、皮肤和衣物直接与其接触。
