Each dish will have two nails. Corrosion Cells and Reactions The special characteristic of most corrosion processes is that the oxidation and reduction steps occur at separate locations on the metal. In these examples, the steel nail corrosion was accelerated when electrically connected to copper and was mitigated when connected to zinc. The deterioration of metals through oxidation is a galvanic process called corrosion. common example of this is iron being oxidized to form what is commonly known as rust.

WebCorrosion is what happens to metals when they are exposed to water and oxygen in the environment. Can someone tell me why - in experiments to observe corrosion of iron nails - we often use a preparation of agar gel (with $\ce{NaCl}$, phenolphthalein, etc.) This means, if a reaction uses up H+ or produces OH-, a pink colour will be observed. 
If you are trying to observe corrosion in a specific area, agar is a convenient way to prevent convection currents from obscuring what caused the corrosion and for localizing the indicator.

WebCorrosion is what happens to metals when they are exposed to water and oxygen in the environment. Can someone tell me why - in experiments to observe corrosion of iron nails - we often use a preparation of agar gel (with $\ce{NaCl}$, phenolphthalein, etc.) This means, if a reaction uses up H+ or produces OH-, a pink colour will be observed. If you are trying to observe corrosion in a specific area, agar is a convenient way to prevent convection currents from obscuring what caused the corrosion and for localizing the indicator. Retrieved March 26, 2020, oxidation) 1. phenolphthalein WebAim: To investigate how different concentrations of sodium chloride affect the rate of corrosion on iron nails. Another effect relates to different metals being present. electrons between the two metals involved occurs through a wire. Add slowly, with constant stirring, 5.0 g of agar.
