Question

Which gas in released when metals react with dilute acids? How will you test that gas?​

Answer:

hydrogen gas

Let's now investigate the reaction between an acid and a metal. You should listen carefully for this 'pop' sound during the investigation. If you hear it, it will signal the presence of hydrogen gas!

Explanation:

hydrogen gas

Dilute acids react with relatively reactive metals such as magnesium, aluminium, zinc and iron. The products of the reaction are a salt plus hydrogen gas. Here's a good way to remember it: MASH (M+A→S+H).
