An electroplating bath is used to plate a uniform layer of silver metal of thickness 0.100 mm onto an object of total surface area 300 cm2. Given that the density of silver is 10.5 g cm^−3, the length of time a current of 2.00 A would need to be passed through the cell to plate the object would be close to ...

This number is ...

A current of 1.85 A was passed through a solution containing X2+(aq) ions for precisely 5.00 minutes. 0.169 g of metallic X was deposited on the inert platinum cathode over this time. Metal X is most likely to be ...

Iron can be galvanised (coated with zinc) using an electrolytic process. The maximum mass of zinc which could be deposited on a corrugated iron cathode in 2 hours using a current of 500 amperes would be ...

During the production of aluminium using the Hall-Heroult electrolytic cell, both the anode and cathode are made of carbon, but the carbon only takes part in the reaction at one electrode. Which of the following correctly identifies the reactive carbon electrode, and the product produced at it during the electrolysis?
