The correct answer is Option C: "It converts electrical energy into chemical energy." This statement is not true about a voltaic cell. Let's break down each of the given options to understand why Option C is incorrect: Option A: The anode acts as negative electrode. This statement is true. In a voltaic cell, the anode is where oxidation occurs, meaning that it is the site where electrons are lost by the reactants. Because electrons are negatively charged, the anode accumulates negative charge relative to the cathode, so it acts as the negative electrode. Option B: The cathode acts as a positive electrode. This statement is also true. In a voltaic cell, the cathode is where reduction occurs, meaning that it is the site where the electrons are gained by the reactants. Since the electrons come from the anode, the cathode acquires a positive charge relative to the anode, and hence it serves as the positive electrode. Option C: It converts electrical energy into chemical energy. This statement is not true and is a characteristic of an electrolytic cell, not a voltaic cell. A voltaic cell, also known as a galvanic cell, operates on the principle of a spontaneous chemical reaction that produces electrical energy. It converts chemical energy into electrical energy, which can be used to do work. Option D: Dry cell is an example of a voltaic cell. This statement is true. A dry cell is a common type of voltaic cell that is used in many household batteries. It generates electrical energy through spontaneous redox reactions occurring within the cell. So, to reiterate, Option C is NOT true about a voltaic cell, as a voltaic cell indeed converts chemical energy into electrical energy, not the other way around.
