For the reduction of silver ions with copper
WebAug 4, 2024 · The reduction of silver ions in this case is difficult, which is due to the complexation of silver ions by the citrate. The formation of silver complexes with citrates has already been described in the literature (Dadosh 2009). In the solution containing silver ions and tannic acid, the peak potential of the reduction of silver is0.173 V. WebIf something gains oxygen, it is said to have been oxidised. So in the equation . . . C + 2CuO CO 2 + 2Cu. . . . the carbon has been oxidised to carbon dioxide. The process of adding oxygen to something is known as oxidation. The opposite of oxidation is called reduction. In the equation, the copper (II) oxide has lost its oxygen.
