This question was asked on Koun Banega Karodpati program.
Question
Which is the chemical also known as burning stone or brimstone as it burns easily ???
1. Sulphur
2. Sodium
3. Phosphorus
4. Potassium
Answer
According to me, all the given chemicals are highly flammable.
Addition to this , Sodium in chemical labs are preserved with caution as it is highly reactive.
Now the question is out of these chemicals which one is known as " brimstone " ??
So I checked with meta AI.
SULPHUR is referred as " brimstone " due to its ability to burn with a blue flame producing sulphur dioxide gas.
When Sulphur burns , it releases a distinctive odour often associated with volcanic activity.
Answer is SULPHUR !!!!
