Investigatory Project

The document is a chemistry investigatory project report submitted by Sai Charitha G for class 12 on studying the effect of metal coupling on rusting of iron. It includes an introduction on corrosion and rusting, the aim and requirements for the experiment, theoretical background on reactions, the procedure, observations made, and a conclusion that coupling iron with more electropositive metals like zinc and magnesium resists corrosion while coupling with less electropositive copper increases rusting.

ACKNOWLEDGEMENT

• I would like to express my special thanks of gratitude to my


teacher Mrs. M Sharda Rao as well as our principal who gave
me the golden opportunity to do this wonderful project on the
topic which also help me in doing a lot of research and I came to
know about so many new things I am really thankful to them.
Introduction
Metals and alloys undergo rusting and corrosion. The process by which
some metals when exposed to atmospheric condition i.e., moist air, carbon
dioxide form undesirable compounds on the surface is known as
corrosion, The compounds formed are usually oxides . Rusting is also a
type of corrosion but the term is restricted to iron or products made from it
.Iron is easily prone to rusting making its surface rough. Chemically, rust
is a hydrated ferric oxide.
Practical 1
Aim: to study the effect of
metal coupling on rusting
of iron.
EXAMPLES
OF
CORROSION:
RESISTANCE
TO
CORROSION
THE
PROCESS OF
RUSTING OF
IRON
1)Two Petri dishes
2) Four test – tube
3) Four iron nails
4) Beaker
5) Sand paper
Requirements 6)Wire gauge
7) Gelatin
for 8) Copper, zinc & magnesium
strips
experiment: 9)Potassium ferricyanide
solution
10)Phenolphthalein.
PROCEDURE
Observations
Experiments done under acidic conditions
Conclusion
• It is clear from observations that coupling of iron with more
electropositive meatal such as zinc and magnesium resists corrosion
and rusting of iron. Coupling of iron with less electropositive metal
such as copper increases rusting.
