二氧化硫的化学式是什么？二氧化硫有哪些化学方程式？

2019-07-29 14:49:40

二氧化硫的化学式为SO2，二氧化硫是折线形分子，键角是119.5°；中心S原子时sp2杂化，两个σ键，一个Π（三中心4电子）。二氧化硫是最常见、最简单、有刺激性的硫氧化物。大气主要污染物之一。二氧化硫常见的化学方程式有如下三种：1．SO2与水的反应SO2+H2OH2SO3 (这是一个可逆反应)，H...

国家二氧化硫排放标准是什么？

2021-06-24 12:54:07

二氧化硫是最常见、最简单、有刺激性的硫氧化物，化学式SO2，无色气体，大气主要污染物之一。火山爆发时会喷出该气体，在许多工业过程中也会产生二氧化硫。由于煤和石油通常都含有硫元素，因此燃烧时会生成二氧化硫。当二氧化硫溶于水中，会形成亚硫酸。若把亚硫酸进一步在PM2.5存在的条件下氧化，便会迅速高效生...
