Question

Which component of the mixture (Fe + S) reacts with dil. HCL and gives hydrogen gas?

Answer 1

Answer:

Your Answer: Iron reacts with dilute HCl and gives Hydrogen gas because it is placed higher in reactivity series of metals than hydrogen. Explanation: a mixture of Iron and sulphur react with hydrochloric acid to form iron chloride and also hydrogen sulphide

Explanation:

Answer 2

Concept Introduction:-

Science is the methodical process of compiling and arranging knowledge about the universe into verifiable, explicable, and predictable hypotheses.

Explanation:-

A question has been provided to us

We need to find the solution to the question

Iron reacts with dilute $HCI$ and gives Hydrogen gas because it is placed higher in reactivity series of metals than hydrogen. A mixture of Iron and sulphur react with hydrochloric acid to form iron chloride and also hydrogen sulphide. When dilute $H_2S$ is added to part A, $FeS$ will react with dil $HCI$ to form $H_2S$ gas which has smell of rotten eggs and will turn lead acetate paper black.

Final Answer:-

The correct answer is Iron reacts with dilute HCl and gives Hydrogen gas because it is placed higher in reactivity series of metals than hydrogen.
