What Is the Connection Between Copper and Sulfuric Acid?
The copper-copper sulfate electrode refers to an electrode composed of a copper rod placed in a saturated copper sulfate solution, and its electrode potential can be calculated by the Nernst formula. Its electrode potential is 0.300V. Generally used for soil and neutral media. It is one of the important components of the cathodic protection device for buried metal components. It is a reference electrode for measuring and controlling the potential of metals in soil media. [1]
- The copper-copper sulfate electrode is formed by placing a copper rod in a saturated copper sulfate solution, and the electrode reaction is:
- CuCu 2+ + 2e
- The electrode potential can be calculated using the following formula:
- In the formula:
- E o standard potential of copper;
- R
- (1) The potential is stable during long-term use;
- (2) Good reproducibility;
- (3) Not easily polarized;
- (4) Long service life;
- (5) Have a certain mechanical strength. [2]
