Question

what is observed when dry rose petals are placed in the jar of sulphur dioxide

Answer 1

In the said query, one of our users asked that what will be observed when dry red rose petals are placed in a jar of sulphur dioxide. In the answer, it was explained that sulphur dioxide is a good reducing agent and decolourises substances in the presence of water. Thus, when moisture is present, then sulphur dioxide will decolourise substances. Fresh rose petals have some moisture content, because of which they can be decolourised by the action of sulphur dioxide.But since the rose petals are dry, therefore they are not decolouirsed by sulphur dioxide. In other words, no action is observed on rose petals. The same has been explained in the answer.
