Introduction:
Corrosion, otherwise called rusting is defined as a natural process that changes over a refined metal to a more chemically stable shape, for example, its oxide, hydroxide, or sulfide. It is the slow destruction of materials (generally metals) by a chemical reaction caused by the environment. Corrosion is basic to ponder in two perspectives. Right off the bat, financial, which including the lessening of material misfortunes coming about because of the squandering ceaselessly or sudden disappointment of funnelling, tanks, metal segments of machines, ships, frames, marines, structures, and so on.:. In addition, is preservation, connected fundamentally to metal assets to world's supply of which is restricted, and the wastage that …show more content…
Saltwater causes rusting because it is a very decent direct that and there are various electrolysis reactions, which makes corrosion to happen. The factor that slows down corrosion is Oil. Oil slows down corrosion because oxygen and molecule could only get through the oil layer; furthermore, oil keeps oxygen particles from crashing on the surface.
Aim:
The Aim of this Investigation is to achieve the chemical reaction of Oxygen and Iron.
Hypothesis:
Independent Variables Dependent Variables Controlled Variables
• Iron wool ball – When it is dipped in various types of liquid it may react to the oxygen in the liquid and chemical changes happen eg: Colour change = rusting • Thermometer – predicting the temperature of the iron wool ball below the room temperature • No substances or variable be kept the same
If the off chance that the Iron wool ball is plunged in various sorts of liquid then the thermometer is embedded into the focal point of the Iron wool ball when it is secured in a paper towel and the rubber band, the iron wool ball will react a specific way.
Materials
• 1x Apron
• 1x Safety Glasses
• 2x 250ml Beaker
• 2x …show more content…
The initial temperature was immediately taken at 0 minutes
9. The timer was started and the temperature was recorded every minute for 10 minutes
10. Written observations were recorded for the appearance of the iron wool ball after the experiment
11. Step: 3 to 10 were then repeated for the liquid substances Oil and Soft drink
12. All materials were disposed appropriately cleared and placed away of the consoles of the experiment
Results
Table 1. Written observations for the corrosion of iron.
Substance Vinegar Saltwater Oil Soft drink
Iron wool before experiment Preceding the investigation the Iron wool ball was Rough, Stringy and a light diminish shading
Iron wool end of experiment • Slight yellow/brown on the paper towel also slightly on the iron wool ball
• Tinge • Orange colour on the paper towel slightly on the iron wool ball • Not much change
• A little yellow • Brown colour
• Slightly on the iron wool ball and paper towel
