when we put burning candle near the mouth of test tube consisting of sulfuric acid piece of magnesium metal why does it explode
Answers
Answer:
-the reaction of sulphuric acid and Magnesium metal is as follows:
Mg + H2SO4 → MgSO4 + H2
-Hydrogen gas is evolved from the test tube in this reaction.
- When we bring the candle near the mouth of the test tube, this hydrogen gas burns explosively in the presence of air with a pop sound.

When we put a burning candle near the mouth of the test tube consisting of sulfuric acid and pieces of magnesium metal, it explodes due to the presence of hydrogen gas.
Magnesium and sulfuric acid react to give magnesium sulfate and hydrogen gas.
The reaction is:
Mg(s) + H₂SO₄(aq) -------> MgSO4(aq) + H₂(g)
When a burning candle is brought near the mouth of a test tube containing hydrogen, it explodes with a pop sound.
It is because hydrogen gas is highly flammable and so it forms an explosive mixture with air.
