Hydrogen gas burns with a pop sound when a lightened matchstick is brought near the mouth of test-tube. (d) Metals react with acids to produce Hydrogen gas. If the gas ignites with a characteristic 'pop' sound, we will know it is hydrogen. Generally, non-metals do not react with acids. 27. a substance that turns one color in a … bitter. hydrogen. Metals that react with these acids produce a metal salt and hydrogen gas: The less reactive metals like Cu,Au,Ag do not react with dilute acids.
