Question

1.02 V; Zn2+(aq) and Ni2+(aq) QUESTION 8 Which of the following processes involves the use of a voltaic as opposed to an electrolytic cell? Note this is a multiple answer question, you can select more the one answer Extracting gold from ore Silver plating cutlery Starting your car Plating chrome onto car bumpers. Using a TV remote. QUESTION 9

Answer 1

ANSWER:

First, we identify the type of cell used in each process:

• Extracting gold from ore => this is done by electrolysis process, the gold in ore (anode) is oxidized to gold ions which migrates to catode electrode where the gold ions are reduced to gold atoms.
• Silver platting cutlery => this is done with an electrolytic cell, the process is called electroplatting
• Starting your car => when you starting your car, you close the circuit thata allows the battery starts to works. This battery is a galvanc cell (when battery is discharged, the car does not start)
• Plating chrome onto car bumpers => this is done using an electrolytic cell, the process is called electroplatting
• Using a TV remote => the batteries in the TV remote are a galvanic cell, where the chemical energy is transformed int electrical energy that makes works the remote.

Then Starting your car and Using a TV remote are the process that involves the use of a galvanic cell.
