Aim: To find the reactivity of metals with acids.
Apparatus: Test tube, dilute hydrochloric acid, magnesium ribbon, spirit lamp. Procedure
1. Take a magnesium ribbon and rub with a sand paper.
2. Put this ribbon into a test tube containing dilute hydrochloric acid.
3. A gas is evolved from the test tube.
4. Now bring a burning match stick near the mouth of the test tube.
5. The gas puts off the match stick and produces a pop sound and gas burns with blue flame.
6. Which indicates hydrogen gas is released.
7. We will get same results with zinc, iron, copper also.
8. Conclusion: Metal reacts with acid and produce hydrogen gas.
