Which among the following is non poisonous in nature?
- A Phosgene
- B Gaseous chlorine
- C Phosphine
- D Red phosphorus
Answer & Solution
Correct Answer
(D) Red phosphorus
Step-by-step Solution
Detailed explanation
Red phosphorus
Phosphorus in the form of red phosphorus is non-poisonous. It's a unique situation. In its pure state, this reddish-violet powder is not poisonous. Under normal conditions, it is stable, but it is combustible and can be ignited by extreme stress or friction.
