Explanation of the reaction between dilute HCl and Zinc:
Heading: Introduction
When dilute hydrochloric acid (HCl) is added to zinc (Zn) pieces taken in a test tube, a chemical reaction occurs. This reaction is an example of a single-displacement reaction, where zinc replaces hydrogen in the acid.
Heading: Observation
The observation made during the reaction is that small bubbles of hydrogen gas (H2) appear on the surface of the zinc pieces. This is because the zinc reacts with the hydrochloric acid to produce hydrogen gas.
Heading: Chemical Reaction
The chemical equation for the reaction between dilute HCl and zinc is:
Zn + 2HCl → ZnCl2 + H2
This equation shows that one zinc atom reacts with two hydrochloric acid molecules to produce one molecule of zinc chloride (ZnCl2) and one molecule of hydrogen gas.
Heading: Explanation
The reaction between zinc and hydrochloric acid is an example of an oxidation-reduction reaction. Zinc atoms lose electrons to form positively charged zinc ions (Zn2+), while hydrogen ions (H+) in the acid gain electrons to form hydrogen gas (H2). The zinc ions combine with chloride ions (Cl-) from the acid to form zinc chloride.
Heading: Conclusion
In conclusion, when dilute hydrochloric acid is added to zinc pieces, small bubbles of hydrogen gas appear on the surface of the zinc pieces. This is due to the reaction between zinc and hydrochloric acid, which is an example of an oxidation-reduction reaction. The chemical equation for this reaction is Zn + 2HCl → ZnCl2 + H2.
