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.

An aqueous sodium chloride solution is electrolyzed using a current of 4.42 A. How much time (min) is required to collect 15.5 L of chlorine if the gas is collected over water at 20.0°C ánd the total pressure is 107.5 kPa? Assume that the water is already saturated with chlorine so no more dissolves. Assume Ptotal(gas) P(Cl2,g) + P(H20,g) and that the correction for column height is negligible. The vapor pressure of water at 20.0°C is 2.34 kPa, F = 96485 C/mol e". and R = 8.314 kPa-L-mol1.K´1 Enter your final answer for the time required in units of minutes.

The Nernst equation is one of the most important equations in electrochemistry. To calculate the cell potential at non-standard-state conditions, the equation is E = E-2.303RTn Flog 10Q where E is the potential in volts, Eo is the standard potential in volts, R is the gas constant, T is the temperature in kelvins, n is the number of moles of electrons transferred, F is the Faraday constant, and Q is the reaction quotient. Using the common reference temperature, 25 °C or 298 K, the equation has the form E = E-(0.0592n)logQ The reaction quotient has the usual form Q = [products]x[ reactants]y A table of standard reduction potentials gives the voltage at standard conditions, 1.00 M for all solutions and 1.00 atm for all gases.
