What is a hypothesis for how pH in water Affects Copper Corrosion?

If the water's pH is more acidic (lower pH) then the effects of copper corrosion will be faster and more pronounce. If the water is less acidic (Higher pH) copper corrosion will take longer and be less pronounce.

Why do copper pipes carry hot water corrode faster than pipes that carry cold water?
Heat speeds up chemical reactions. As corrosion is a chemical reaction, copper pipes at a higher temperature will corrode faster
Why does copper II sulfate pentahydrate lose its blue colour once heated?
The 5 water molecules are driven off by heating and the central Copper atom is no longer complexed by the water molecules which affects the energy and hence the color of the resulting anhydrous Copper Sulfate.
Does copper rust or not rust?
No, Copper Does Not Rust... It CorrodesHowever, it will oxidize and turn dark brown and then green over time. The Statue of Liberty looks green because copper has a property of turning green due to carbon dioxide and the moisture in the air. That is not rusting; it is called copper patina. More infoExposure to air or oxygen causes the brownish film on copper piping. Water - especially mineralized water - causes greenish or bluish corrosion. And deionized water can pull copper metal from the piping and cause pitting or damage.The term "rusting" is reserved for the corrosion of iron.Copper does not rust. Rust is a mixture of hydrated iron oxides so, by definition, if will only form on iron and iron-rich materials (such as some types of steel). Copper can get a covering of Verdigris, which is a green-colored compound.
What is the hypothesis of the desalination of water?
The hypothesis is the water that collects is going to be salt free.
What metals are most affected and least affected by metal corrosion What causes metal corrosion Hows is metal corrosion caused by water and how is it related to it?
Corrosion is a chemical reaction; corrosion of iron is the reaction with water in the presence of oxygen. Metals as Pt, Au, Ta, Rh, Ru, etc are less sensible to corrosion.
How does salt water affect copper?
Salt water affects copper by causing corrosion. The non-oxidizing acids in the salt water break down the copper metal and in turn, the metal loses its color and begins to rust.
How do you store copper?
Copper can be stored in bottles containing water, such that none of the copper is exposed to air, as this can cause the corrosion of copper.
What is the long term impact of water and oxygen on copper?
Corrosion or the coper item resulting in holes or structurally weakened copper. It turns very green; like the statue of liberty which is also made of copper. It should be cleaned with acid to remove corrosion.
What causes the green sludge inside your copper pipe at the connection site to your hot water tank?
the green sludge is the result of copper pipe corrosion. it's a copper oxide
Why Copper Nickel alloy is preferred for marine operations?
The copper nickel alloy is preferred for marine operation because of its good resistance to sea water corrosion.
How pH affects copper corrosion?
A lower pH will erode a copper heat exchanger in a heater very quickly. I will also then, increase the copper level in the pool water and will make it difficult to add pH increaser or TA increaser. Both chemicals will stay out of solution. Once they do deslove the copper drops out and the will stain the liner black. The best solution is to keep an eye on your pH especially when you have a heater.
Why does your well water turn tub green?
It's the copper in old plumbing. The acidity of the water or just age can cause corrosion, releasing copper into the water. You can replace with PVC, or get a filtration system, or just drink bottled water, if you're concerned about it.
What chemical in copper makes it rust?
The only chemical that could make something rust is iron; "rust" refers specifically to the corrosion of iron, so copper cannot rust. However, its corrosion is caused by copper itself being oxidised and forming compounds which are water soluble and also easier to damage.
What is in your water that stains sink blue-green?
Probably copper. This may be caused by your water being acidic and reacting with the copper in your pipes. You may have to get the pH of your water tested if it below 6 then the water is too acidic. Although small amounts of copper in your water is not harmful to your health corrosion in your pipes may eventually lead to leaks.
Does water affect pennies?
As pennies are not made of iron, they cannot rust under any circumstances.However they can corrode. The copper shell will produce a green corrosion product, the zinc core can corrode completely away as a transparent water soluble corrosion product. This corrosion will be very slow in plain water (much slower than iron rusts in water) but will be much faster if an acid is added to the water.
Why do copper pipes carry hot water corrode faster than pipes that carry cold water?
Heat speeds up chemical reactions. As corrosion is a chemical reaction, copper pipes at a higher temperature will corrode faster
What causes electrolysis in plumbing?
Electrolysis in plumbing affects the copper pipes used. If electrical wiring is installed too closely to copper water pipes, the electrical current running through the wiring charges to copper piping combined with the water and its properties causes electrolysis in the copper water pipes thereby weakening them.
