Concept introduction:
Electrolytic Cell:
The device, which is used to convert the electrical energy into chemical energy, is known as electrolytic cell and this type of cell are works under the principle of electrolysis.
Electrolysis molten salt:
The decomposition of chemical by passing through an aqueous solution of ions is known as electrolysis.
Half cell reaction:
In
In oxidation the species lose its electron and in cathode the species gain electrons in cell reaction.

- An aqueous solution of KBr is placed in a beaker with two inert platinum electrodes. When the cell is attached to an external source of electrical energy, electrolysis occurs. (a) Hydrogen gas and hydroxide ion form at the cathode. Write an equation for the half-reaction that occurs at this electrode. (b) Bromine is the primary product at the anode. Write an equation for its formation.arrow_forwardPredict the chemical reactions that will occur at the two electrodes in the electrolysis of an aqueous sodium hydroxide solution.arrow_forwardAs an example of an electrolytic cell, the text states: Sodium chloride is electrolyzed commercially in an apparatus called the Downs cell to produce sodium and chlorine. This is a high-temperature operation; the electrolyte is molten NaCl. Write the half-reaction equations for the changes taking place at each electrode. Is the electrode at which sodium is produced the anode or the cathode? The Downs cell electrolyzes molten melted sodium chloride, producing sodium and chlorine.arrow_forward
- Gold is produced electrochemically from an aqueous solution of Au(CN)2 containing an excess of CN. Gold metal and oxygen gas are produced at the electrodes. What amount (moles) of O2 will be produced during the production of 1.00 mole of gold?arrow_forwardWhat mass of each product is produced in each of the electrolytic cells of the previous problem if a total charge of 3.33105 C passes through each cell? Assume the voltage is sufficient to perform the reduction.arrow_forward
