How fast will copper tarnish in fresh water?

Answer 1

Copper exhibits good resistance to corrosion in urban, marine, and industrial atmospheres. The major factors that control the initial rate of attack on copper are moisture, temperature, and the level of pollution. Soon after exposure of copper to the atmosphere copper oxidize, the bright copper surface takes on a dull tan tarnish. After a few years thik tarnish gradually changes to dark brown or black. At a later stage the corrosion products of copper turn green. The corrosion rate of several types of copper in a 20-yr test averaged 1 pm/yr (0.05 mpy) in an industrial atmosphere, 0.8 pm/yr (0.03 mpy) in a marine atmosphere, and 0.5 pm/yr (0.02 mpy) in a rural atmosphere

Answer 2

Copper can start to tarnish in fresh water within hours to a few days, depending on the presence of oxidizing agents or pollutants in the water. Factors like pH levels, temperature, and oxygen content can influence the rate of tarnishing. Regular cleaning and polishing can help maintain the appearance of copper items in fresh water.

Answer 3

Oh, dude, copper will tarnish in fresh water over time because of oxidation and all that fun chemistry stuff. It's like, not an instant process, so don't expect your shiny copper to turn green overnight. Just give it some time, and eventually, you'll have that rustic, vintage look you never asked for.

Answer 4

Well, honey, copper can start tarnishing in fresh water pretty quickly depending on the conditions. It might take a few days to a few weeks for that shiny copper to start looking a little green and grimy. So, if you want to keep your copper looking like a million bucks, you better keep it dry and polished.
