Electrolytic cells use electricity to cause a nonspontaneous redox reaction to occur. An electrolytic cell is constructed using the following components: . a power source, such as a battery, • the substance that will undergo electrolysis, and • two inert electrodes (usually platinum), which serve as the electrical connection between the power source and the substance undergoing electrolysis. As with any cell, oxidation occurs at the anode and reduction occurs at the cathode. The oxidation of water, which produces oxygen...

HL Questions on Electrochemical cells (2) (AHL) - Electrolysis H.504 lectricity was passed through two different electrolytic cells connected in series. One of the cells contained dilute suffuric acid solution and 250 cm3 of oxygen (measured at STP) was evolved at the positive electrode (anode). The second cell contained molten lead bromide. (I mole of gas occupies 22.7 dm3 at STP) (a) Deduce the volume of hydrogen that was released (measured at STP) at the negative electrode (cathode) in the...
