Anode

The transcript explains the role of the anode in different contexts. In devices that consume power, the anode is positive, while in devices that provide power, it is negative. In electrolysis, the anode is connected to the positive terminal of an external electric supply and attracts negative ions, which release electrons to the anode.

In a device that consumes power, what is the charge of the anode?

• Negative

• Positive

• Variable

• Neutral

What is the charge of the anode in a device that provides power?

• Variable

• Neutral

• Negative

• Positive

In electrolysis, to which terminal is the anode connected?

• Negative terminal

• Positive terminal

• Neutral terminal

• Variable terminal

What type of ions does the anode attract during electrolysis?

• Variable ions

• Neutral ions

• Negative ions

• Positive ions

What happens to the negative ions when they reach the anode in electrolysis?

• They split into atoms

• They remain unchanged

• They lose electrons

• They gain electrons
