Question

Is there a difference in the way metals
and non-metals react with acids? What
- could the 'pop' sound in some cases be
due to when a burning match stick is
brought near the mouth
of the test tubes?
You must have found that non-
metals generally do not react with acids
but metals react with acids and produce
hydrogen gas that burns with a 'pop'
sound. You must have noticed that
copper does not react with dilute
hydrochloric acid even on heating but
it reacts with sulphuric acid.​
