Q. Which is more stable Cu+ or Cu2+?
Cu2+ is more stable than Cu+.Stability depends on the hydration energy (enthalpy) of the ions when they bond to the water molecules. The Cu2+ ion has a greater charge density than Cu+ ion and thus forms much stronger bonds releasing more energy.
Q. What is the name for Cu2+?

Q. Is Cu2 a Cu or copper?
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.
Q. How do you test for copper levels?
Blood and urine tests. Blood tests can monitor your liver function and check the level of a protein that binds copper in the blood (ceruloplasmin) and the level of copper in your blood. Your doctor also might want to measure the amount of copper excreted in your urine during a 24-hour period.
Q. What’s more expensive copper or brass?
UPDATE: Which is most expensive, Brass, Bronze or Copper? While it can vary depending on which grades you are comparing, typically copper is the most expensive of the three red metals. While all three contain copper, the percentage is far lower in Brass and Bronze than in pure copper as alloying elements are mixed in.
Q. How strong is red brass?
1 What is Considered Red Brass?…Physical and Mechanical Properties of Red Brass.
| Properties | Metric | Maximum |
|---|---|---|
| Melting point-solidus | 988°C | 1810°F |
| Density (@20°C/68°F) | 8.75 gm/cm3 | 0.316 lb/in3 |
| Tensile Strength | 269-724 MPa | 39-105 ksi |
| Yield Strength | 69-434 MPa | 10-70 ksi |
Q. What is red brass commonly used for?
Red brass is popular because of its favorable combination of casting properties, machinability and general utility. Red brass is commonly used for castings, valves, pipe fittings, water pumps, meter housings, small gears and high-quality plumbing goods.
Q. What is considered dirty brass?
Dirty brass generally has foreign contaminants such as paint, oil, and other metals. Glass and wood can also cause your brass to be considered as dirty. If there is copper attached to your brass materials, this generally does not cause it to be qualified as dirty.
Q. How can you tell the difference between red and yellow brass?
The main difference between red and yellow brass is the copper content. If you are unsure which type of brass is which, use a rasp or file to lightly sand an inconspicuous place on your copper item. Orange residue denotes red brass and shavings of a pale yellow hue demonstrate that the object is yellow brass.
