Primary Battery: A Silver-oxide battery is typically used to power small devices such as a wristwatch. This is a type of primary battery (not rechargeable). A new battery contains 0.5 grams of zinc metal (Zn) and 1.75 grams of silver oxide (Ag20). Assume the battery is completely exhausted after 15,000 hours (all of the limiting reagent has been consumed). Battery reactions: Zn + 20H => Zn(OH)2 + 2e Ag:0 + 2H* + 2e => 2Ag + H20 Determine the following: a) Identify anode and calculate moles of anode material in new battery b) Identify cathode and calculate moles of cathode material in a new battery c) Identify limiting reagent

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
