✔ 最佳答案
在HKCEE程度,SO2,Cl2,NH3會有 pungent smell,Burning sulphur 都會有pungent smell,是因為燃燒時產生的SO2

CE入面就SO2,Cl2,NH3都會有pungent smell,Burning sulphur都會有pungent smell,是因為燃燒時產生的SO2
上面講左呢d,
我想補充,
你有無留意SO2,Cl2,NH3都係酸或鹼性氣體,
呢d較弱ge酸或鹼會刺激你ge respiratory system,所以會咳

There are a lot chemicals having pungent smell, NH3 rates number
one. Vineger, HS2 also have pungent smell. Surfur containing com-
pounds do have foul odor of decaying fish such mercaptan. The
pungent smell is a naturally defending signal to warn us that there
is a toxic chemical around.
