✔ 最佳答案
Sulphuric acid當然唔係bleaching agent啦~其實係 SO2 加入水後,出左SO3**,即係Sulphurous acid .
SO3** + H2O => SO4**+ 2H" +2e*
Bleaching Properties
SO3** + dye(colour) => SO4** + (dye - O /colourless)
但係e個reaction係不持久的(not permanent)

Sulphuric acid is not a bleaching agent...
Sulphurous acid and sulphur dioxide are bleaching agents...
They are strong reducing agent...
The dye is reduced and become colourless...
