CBSE Class 10 Science 2020 · Paper 31/C/1 · Question 17(b)
Draw a labelled diagram of the experimental set-up to study the action of steam on a metal. Name the gas produced in the reaction.
Answer
Steam passed over a heated metal in a boiling tube gives hydrogen, collected over water in an inverted test tube.
Labelled diagram: a boiling tube clamped to a stand holds glass wool soaked in water at its closed end and the metal sample (iron filings or zinc granules) in the middle; a burner heats the metal strongly, so steam from the wet glass wool passes over it; a delivery tube passes through the cork at the mouth and leads under water in a trough, up through a beehive shelf, into an inverted test tube filled with water, where the gas collects by pushing the water out. The gas produced is hydrogen, for example .
