First the pipe and cap must be dry. There can be no water the pipe that will be close enough to the joint to feel the heat.
You will need Soldering Flux, Solder, Emory Paper and a hot Torch. Turbo Torch is a good one, if you use MAPP Gas.
Sand the pipe with the Emory Cloth until it is clean and shiny all the way around. (The width of the cloth is fine.) Sand the Cap the same way. Put Flux on the copper pipe and inside the cap. Put the Cap on the pipe, push it all the way down.
Take the torch and heat the cap on it's side in one spot while holding the Solder on the opposite side at the point where the bottom of the cap and the pipe meet. When the joint is hot enough the solder will melt and start to draw into the joint. After a few more seconds remove the heat and melt solder all the way around the joint in one quick motion. You can wipe the joint with a rag if you like to make it look better before the solder hardens. Don't use Nylon or any other cloth that might melt.
You can remove corrosion from copper pipes by using a fine sandpaper or a wire brush to gently scrub the affected area. You can also create a paste using equal parts vinegar, salt, and flour, apply it to the corroded area, and let it sit for a few hours before wiping it off. After removing the corrosion, make sure to rinse the area thoroughly with water.
Corrosion implies that the material of the pipe has already been removed, if it continues the pipe will eventually disintegrate. Therefore you can not remove "corrosion", you can only replace the pipework with new copper.You can however add chemical to prevent corrosion from happening in the first place, ot stop its progress.

What is the word equation for corrosion of copper?
The word equation for the corrosion of copper is: Copper + Oxygen + Water → Copper Oxide.
What metal turns green and why?
Copper is a metal that turns green when exposed to air and moisture due to a chemical reaction forming a patina. This patina is a protective layer that forms on the surface of the copper, acting as a barrier against further corrosion.
What is the balanced equation for corrosion of copper?
The balanced equation for the corrosion of copper is: 2Cu(s) + O2(g) + H2O(l) + 2e- -> 2Cu2+(aq) + 2OH-(aq)
What is a hypothesis for how pH in water Affects Copper Corrosion?
A hypothesis could be that as the pH of water decreases (becomes more acidic), the rate of copper corrosion increases. This is because lower pH levels can increase the availability of hydrogen ions which can accelerate the oxidation of copper. Conversely, at higher pH levels (more basic), the corrosion rate may decrease due to the formation of protective oxide layers on the copper surface.
Can you join copper and cast iron without a dielectric union?
No, it is not recommended to directly join copper and cast iron without a dielectric union. Without a dielectric union, the dissimilar metals can create galvanic corrosion due to electrolysis, potentially leading to pipe damage and leaks. Using a dielectric union will prevent this type of corrosion by separating the metals with a non-conductive barrier.
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
Is it common to get a pin hole leak in a copper pipe that is less than 5 years old?
It depends on the condition of the pipe. Corrosion could cause a leak.
What is the word equation for corrosion of copper?
The word equation for the corrosion of copper is: Copper + Oxygen + Water → Copper Oxide.
How do you remove barb fitting on cooper pipe?
Either cut it out on the pipe with copper cutters or sweat it out with a plumbing torch.
How do one eighth inch diameter holes come to appear in copper water supply pipes that are under two feet of earth and a 4 inch concrete slab?
The copper pipe is reacting with metallic elements in the ground which in turn creates oxidation in the copper, which causes corrosion, which leads to holes in the copper pipe.
Is copper pipe a pure substance?
100% pure metal is actually quite difficult (some may argue impossible) to achieve. Copper pipe can be produced from one of 5 alloys under the "Standard Specification for Seamless Copper Pipe". They range from being 99.9% pure copper to containing a maximum of 0.04% phosphorus. While in a laboratory it would not be considered pure, in everyday life. . . copper pipe is basically all 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.
Cause of pinholes to quarter inch holes in copper pipe all 16 leaks in 16 hot and cold pipes are at the plate where the pipe enters the apartment from the crawlspace vertically?
Electrolysis created from two dissimilar metals touching each other. This creates corrosion and breakdown of the properties of the copper pipe. Replace the copper and place some type of sleeving around the pipe when reinstalling.
What is the most common plumbing problem?
The most common problem I encounter is copper pipe corrosion. A close second is worn seats in taps.
Why is the pipe carrying the hot gases made of copper coil?
Copper is often used for the coil in a gas pipe because it has good thermal conductivity, meaning it can efficiently transfer heat from the hot gases. Copper is also resistant to corrosion and can withstand high temperatures, making it a suitable material for this purpose. Additionally, copper is malleable, which allows for easy shaping and installation of the coil in the pipe system.
How do you remove red stencil from copper pipe?
Sand it lightly with very fine sandpaper
Can copper turning be used to test how pH affects copper corrosion?
Yes, copper turning can be used as a test specimen to observe the effects of pH on copper corrosion. By subjecting copper turnings to different pH solutions and monitoring the rate of corrosion, one can determine how pH influences the corrosion of copper. This experiment can help in understanding the behavior of copper in different environments.
