8/23/2023 0 Comments Copper will rustResearch is still being done on the effect of pH on corrosion due to the severity of the issue that will eventually be a worldwide problem. Scientists are figuring out how they can use orthophosphoric acid to protect pipes instead of using zinc orthophosphate. Many copper pipes have zinc orthophosphate because it is used to reduce the amount of corrosion from copper pipes, but zinc orthophosphate is expensive. Another thing that people have started using to eliminate copper corrosion is the use of zinc orthophosphate. “Many communities nationwide use zinc orthophosphate.” (Water Research Foundation. The water is too corrosive for the protective coating on the pipes to have any sort of benefit of protecting the pipes. Lead poisoning can occur because the protective coating on the pipes that the water is brought in on is starting to dissolve due to the acidity of the water. Another reason for protective coating on copper pipes is to reduce lead poisoning. This protective coating helps the copper pipes so that the pipes do not corrode as quickly as they might if there was no coating. Another scientist states that if pH has gone bad, it can lead to the destruction of the coating on the copper pipes. “If the pH goes bad too long, the protective coating can start to break down, and you can start to get leads in the drinking water.” (Margevicius. The scientists conclude that the water is turning brown because it was corroding the metal pipes that carry the water to a person’s house. Scientists in the area notice that the water’s pH has gone down because of this new found lower pH. “The raw water’s pH, a measure of acidity or lack thereof, had plummeted, nearing a level in which it would be acidic.” (Tony Briscoe. The people have noticed that their water is slightly brownish/yellowish. Citizens in Cleveland have noticed that their water supply from Lake Erie has discoloration in it. Research has been done that states that when water is more acidic it tends to corrode pipes. Get original essay Previous and current researchĬopper tends to be more corrosive when liquids have a lower pH higher acidity. Copper corrosion is affected greatly by the pH of a solution. The acidic rain-when in contact with copper-turns the original color of copper to a dull, green color. Acid rain is caused by humans polluting water systems. The Statue of Liberty has turned green over time due to acid rain. This happens because when copper responds to different elements, it creates a chemical reaction copper is turned green. When copper and acids react, copper turns green. Common identifiers of copper in water include blue tints in water, metallic tastes, or has a distinctive odor to it. Due to the acidity in water, copper pipes corrode, leading to a large amount of copper in drinking water. When water has a low pH, it tends to corrode pipes as well. Copper appears in water because water is corrosive and when there are pipes that carry strong flows of water, the pipes corrode. Most people receive a majority of copper in the water that they drink. Copper is essential for a human to stay healthy, although too much copper can be harmful. “On average, most people will eat and drink about 1,000 micrograms (μg) of copper per day” (Winter M. The element copper is a necessity for humans, people need to have a small amount of copper in their diet.
