What is Anode?
| Negative Electrode |
|
The negative electrode of a battery (or other device). 1. The electrode where oxidation occurs in an electrochemical cell. It is the positive electrode in an electrolytic cell, while it is the negative electrode in a galvanic cell. The current on the anode is considered a positive current according to international convention; however, in electroanalytical chemistry the anodic current is often considered negative. Contrast with cathode. 2. Magnesium anodes prevent tank failure due to corrosion. Corrosion is essentially a flow of electric current. By placing an anode into the tank, the current from the anode will make the surface of the tank cathodic and prevent metallic icons going into solution and thereby corroding. A naturally induced voltage is created due to the potential differences between various materials. What to do?: It is important that the anodes in the water heaters are checked regularly because sacrifice themselves in this process and could be used up at a slow or more rapid pace. They should be replaced before having dissolved more than 2/3. |
