Copper corrosion caused by potassium or sodium chloride water treatment
We have copper tubing that circulates refrigerant through them. We have had instances when the copper has been corroded on the outside surface. It turns a nice green color. Will the potassium and or sodium chloride attack the copper tubing?

Chlorides are among the most active ions in nature. They will corrode all but the precious metals such as gold, platinum, iridium, etc.
