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

Experiment No. 3: Electrochemistry and Corrosion Date Performed: November 4‚ 2010 CONCLUSION Electrochemistry is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor and an ionic conductor and which involve electron transfer between the electrode and the electrolyte or species in solution. Basically‚ an oxidation-reduction reaction (redox reaction) is a reaction in which electrons are transferred between species or in

1.Is technology alone enough to ensure high quality customer service? - Technology alone is not enough to ensure high quality customer service‚ but if properly utilized it can be a great tool to monitor that high quality customer service is offered. It must be the people working in the industry hand in hand with the modern technology who must do the right job to make sure they are offering high quality customer service. 2.improvements in artificial intelligence technologies will result in decline

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.

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

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

Acrylic nails are a great option for someone who has a habit of biting her nails or for those who have trouble growing their nails. Some women will use these types of nails to help break the habit of nail biting; other women will use them so they can feel beautiful and have lovely‚ easy to care for nails. Acrylics can stand up to the abuse that we as women put our nails through on a daily basis. Acrylic nails are by far the most popular type of artificial nail on the market today. These nails can completely
