which of the following statement are true for all electric cells?
I. electrons flow from the anode to the cathode
II. reduction occurs at the anode
III. oxidation occurs at the cathode
IV. oxidation occurs at the anode
V. reduction occurs at the cathode
A. I,IV and V B. I,II and III C. II and III D. IV and V E. I and III
Oxidation occurs at the anode and the anode is negative. Reduction occurs at the cathode and it is positive. From this you know IV and V are correct. Electrons flow from the ..... to the .....
To determine which statement is true for all electric cells, let's analyze the given options:
I. Electrons flow from the anode to the cathode: This statement is true for all electric cells. Electrons are negatively charged particles, and they flow from the anode (negative electrode) to the cathode (positive electrode) in an electric circuit.
II. Reduction occurs at the anode: This statement is false. Reduction occurs at the cathode, where electrons are gained, and the positive ions are reduced.
III. Oxidation occurs at the cathode: This statement is false. Oxidation occurs at the anode, where electrons are lost, and the negative ions are oxidized.
IV. Oxidation occurs at the anode: This statement is true for all electric cells. As mentioned earlier, oxidation occurs at the anode, where electrons are lost.
V. Reduction occurs at the cathode: This statement is true for all electric cells. Reduction occurs at the cathode, where electrons are gained.
Based on this analysis, the correct answer is Option E. Therefore, the true statements for all electric cells are:
I. Electrons flow from the anode to the cathode
III. Oxidation occurs at the anode.
