a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron strip to fully corrode.

CORROSION Corrosion is defined as the involuntary destruction of substances such as metals and mineral building material by surrounding media‚ which are usually liquid (i.e. corrosive agents)." Most metals corrode. During corrosion‚ they change into metallic ions. In some cases‚ the product of corrosion itself forms a protective coating. "For example‚ aluminium forms a thin protective oxide layer which is impervious to air and water. In other cases (e.g. iron)‚ however‚ the coating either flakes

Rust is the name given to the common compound (Fe2O3) when iron combines with oxygen to form iron oxide. Rusting is known as corrosion of iron and its alloys such as steel or cast irons. Rust can be found on cars‚ metal pipes‚ aircrafts and anywhere with iron‚ copper and aluminium. Corrosion can be concentrated locally to form a split or crack‚ or it can extend across a wide area which causes corroding on surfaces. Because corrosion is a diffusion-controlled process‚ it occurs mainly on exposed surfaces

Galvanic Corrosion in the Statue of Liberty Introduction: The Statue of liberty built by Gustav Eiffel and Frederic Bartholdi in 1886 was made of materials that consisted of a wrought iron framework with an outer cladding of copper attached by saddles of copper. It was pretty much anticipated that galvanic corrosion would occur so both of the metals were separated by an insulation known as “asbestos and shellac” insulation (Shellac is a natural resin that was widely used in the Victorian

How to do a Deadly EEI in Chemistry Students: These are some hints about the requirements of a high quality Extended Experimental Investigation for the Queensland Senior Chemistry Syllabus. Guidelines given to you by your teacher should take precedence if there is any doubt. They are addressing a Year 12 EEI but will still guide you for Year 11. They refer to a hypothesis-testing EEI. What’s the purpose of an EEI? You‟ll do an EEI to research a question you have about some chemistry-related phenomena

Chemistry EEI Introduction: Corrosion is the returning of metals back into their natural constituents when exposed to an atmosphere with which it can react. Both metals and non-metals are able to undergo redox reactions as well as other ceramics and polymers which are known to undergo a similar process which is referred to as degradation. This investigation aims to outline and assess the factors affecting corrosion and explore in depth how redox reactions work. Reduction and oxidization reactions

EEI Corporation (EEI) was incorporated on April 17‚ 1931 as a machinery and mills supply house for the mining industry. The Company eventually expanded into provisioning construction services and a broader range of industrial machinery and systems. EEI is a member of the Yuchengco Group of Companies‚ a conglomerate with interests in banking‚ financial services and property development. EEI has been involved in the installation‚ construction and erection of power generating and transmission facilities

Name: Hannah Crome Introduction Corrosion is the oxidation of metals by materials in their environment. Rust is the corrosion of iron by oxygen in a moist environment. Corrosion has many effects on the properties of metals‚ corroded buildings‚ or machinery can develop weaknesses that result in malfunctions or breakages. Corroded metal can also not conduct electricity‚ which again can interfere with the functions of that metal. Aim: the aim of this experiment is to evaluate the effect
