Question

The metal which produce hydrogen gas on reaction with dilute hydrochloric acid where as sodium hydroxide solution is copper aluminium iron sodium

Answer 1

Na, Al, and Fe will.. produce H2 bcz they are more reactive then H so reduce it in H2

Answer 2

Answer:

Aluminium is a reactive metal and it is known to react with dilute hydrochloric acid and sodium hydroxide solution to produce hydrogen gas.

Explanation:

This is because of the position of aluminium in the electrochemical series that makes it highly reactive and also explains its ability to displace hydrogen gas from both the given reactants.

Elements which are placed above hydrogen in the series can easily displace it from the respective compounds.
