Which element produces hydrogen on reaction with strong alkali?a)Sib)...
Reaction of Element with Strong Alkali:
Hydrogen gas is produced when certain elements react with strong alkali. In this case, the element that produces hydrogen on reaction with strong alkali is sulfur (S).

Explanation:
- When sulfur reacts with strong alkali, such as sodium hydroxide (NaOH), hydrogen gas is produced.
- The chemical equation for the reaction is:
S + 2NaOH → Na2S + H2O + H2
- This reaction is a redox reaction where sulfur is oxidized and sodium is reduced.
- The hydrogen gas produced in this reaction can be collected and tested by the pop sound test, as hydrogen gas is flammable.

Importance of Identifying the Element:
- Identifying the element that produces hydrogen gas on reaction with strong alkali is important in various chemical reactions and industrial processes.
- Understanding these reactions helps in predicting the products formed and the behavior of different elements in chemical reactions.
In conclusion, sulfur is the element that produces hydrogen on reaction with strong alkali, and understanding this reaction is crucial in the field of chemistry.
