"WebRemember oxidation occurs at the anode. And you can remember that by an ox. The zinc electrode is our source of electrons. So this is our negative electrode, and those electrons move in our wire to produce an electric current. When those two electrons reach our copper electrode, we know we have copper two plus ions in solution. " - In an electrolytic cell is the anode positive

In an electrolytic cell is the anode positive

WebJun 25, 2024 · Yes, an electrolytic cell’s anode is positively charged (and the cathode is negatively charged). Despite the negative charge, oxidation occurs at the anode. The chemical reactions that take place in these electrochemical cells are not spontaneous. Question 5: What are electrolytic cells? Answer: WebIn an electrolytic cell, the anode is the wire or plate upon which excess positive charge is imposed. [2] As a result of this, anions will tend to move towards the anode where they will undergo oxidation. Historically, the anode of a galvanic cell was also known as the zincode because it was usually composed of zinc. [3] [4] : pg. 209, 214
