Scientific Report

Introduction
This scientific document provides a brief overview of a sample experiment designed to
demonstrate the structure of a formal report. The topic chosen is the reaction between acids
and metals, a common introductory experiment in chemistry.

Objective
To investigate the reaction between hydrochloric acid (HCl) and zinc (Zn), and to identify
the products of the reaction.

Materials and Methods


Materials:

 • Zinc granules
 • Dilute hydrochloric acid (2M HCl)
 • Test tube and stopper
 • Delivery tube
 • Gas jar
 • Burning splint

Method:

1. Place a few zinc granules into a test tube.


2. Add dilute hydrochloric acid and quickly place the stopper with the delivery tube.
3. Collect the gas produced in the gas jar.
4. Test the gas with a burning splint.

Results
When zinc reacts with hydrochloric acid, effervescence is observed. A gas is produced that
relights a burning splint with a 'pop' sound, indicating the presence of hydrogen gas. The
solution gradually turns into zinc chloride.

Equation
Zn (s) + 2HCl (aq) → ZnCl₂ (aq) + H₂ (g)

Conclusion
The experiment confirms that the reaction between a metal (zinc) and an acid (hydrochloric
acid) produces a salt (zinc chloride) and hydrogen gas. This is a characteristic property of
metal-acid reactions.
