Metal Reactivity with HCl Study

This chemistry report investigates the reaction of different metals with hydrochloric acid, focusing on the reactivity series and the production of hydrogen gas. The experiment aims to measure the time taken for various metals, including magnesium, zinc, aluminum, and copper, to react with hydrochloric acid, hypothesizing that more reactive metals will react faster. The report concludes that as reactivity increases, the reaction time decreases, and suggests further trials and a broader range of metals for more accurate results.

Introduction
This experiment investigates the reaction of different metals. It is conducted in the
chemistry lab. The experiment is based on the reactivity of metals according to the
reactivity series. Metals always produce heat as it will be an exothermic reaction.
Different metals react with hydrochloric acid to produce hydrogen gas and metal
chloride. The reactivity of the metal affects the rate of hydrogen gas production. The
more reactive the metal, the faster the reaction.

Research question :
What is the effect when a metal reacts with hydrochloric acid? { magnesium, zinc,
aluminum, copper }

Aim:
The investigation aims to measure how long different metals take to react with
hydrochloric acid.

Hypothesis :
As the reactivity increases the time will decrease. Magnesium will react quickly however
zinc may take longer to react as it is lower on the reactivity series. When metals react
with HCl there will be heat produced.

Variables :

independent variable: metals

Dependant variable: time, reaction


2

Controlled variable: HCl, room temperature

Explanation of the following Variables :


independent variable is metals as different metals will be tested.

dependent variable is the time taken for each reaction to take place and how it reacts

controlled variable is the amount of HCl and the temperature that is being kept the same

Apparatus :
● Beaker
● Surgical gloves
● Hcl { DILUTED }
● Aluminum
● Magnesium
● Copper
● Zinc dust
● Dropper
● Timer
● Test tubes

Procedure :

1. wear surgical gloves on both hands


2. Take 3 test tubes
3. Fill the first test tube with aluminum
4. Fill the second tube with magnesium
5. Fill the Third tube with zinc dust
6. With a dropper add 1.5 ml of Hcl { DILUTED } to the first test tube
3

7. Start the timer directly after


8. Wait until the reaction is complete
9. Stop the timer
10. Repeat the same procedure for all the other test tubes
11. Record the results in the data table

HAZARDS :
HCl MAY BURN SKIN AS A PROTECTION WEAR HAND GLOVES.

HCl MAY BURN EYES WEAR EYEWEAR.

TRY TO MEASURE EXACTLY 1.5 ML FOR ACCURATE RESULTS.

CONCLUSION:
As the reactivity increases the time decreases. Magnesium will react quickly however
zinc takes longer to react as it is lower on the reactivity series. When metals react with
HCl heat is produced.

Evaluation :
LIMITATIONS - SUGGESTIONS

● If taken only one trial results may not be true


1. TAKE MORE TRIALS TO GET ACCURATE RESULTS
6

● Only a few types of metals were taken, and no diversity in results


2. TAKE MORE METALS FOR A RANGE OF RESULTS

Extension
● Take another kind of controlled Variable ( acid )
● Investigate different varieties of metals
● Try with varying amounts of acid

It produces a hydrogen gas. This experiment can be helpful for powering


vehicles, industrial uses and environmental applications. Metal salts can be used
for various medical applications, such as water treatment, agriculture,
photography, electronics, glass, and ceramics.
