WebMar 13, 2024 · Galvanic cells need not to be "separated" as you state. What has to be separated is not the cells, but the half-cells. In the Daniell cell, Zinc is the anode and emits electrons which move through the external circuit. But this phenomena also produces Z n X 2 + ions in solution. This is only possible if some negative ions are present in solution. WebA familiar example of electrolysis is recharging a battery, which involves use of an external power source to drive the spontaneous (discharge) cell reaction in the reverse direction, restoring to some extent the …

WebIn an external circuit of an electrochemical cell, electrons flow Select one: A. from the cathode to the anode. B. from the anode to the cathode C. only through the salt bridge. D. from right to left. B. from the anode to the cathode. A galvanic cell must be constructed with an anode and cathode that Select one: WebAn anode is an electrode of a device through which conventional current (positive charge) flows into the device from an external circuit, while a cathode is an electrode through which conventional current flows out of the device. If the current through the electrodes reverses direction, as occurs for example in a rechargeable battery when it is ... a7 捷運站
