Question

Voltaic Cell (3)

Not quite remember

I easily remember

The movement of electron in a voltaic cell

Electrons flow from the negative terminal to the positive terminal; while the current flows from the positive terminal to the negative terminal

Definition of anode

Anode are electrodes where oxidation occurs

Definition of cathode

Cathodes are electrodes where reduction occurs

Another name for negative terminal in a voltaic cell

In a voltaic cell, the negative terminal is also known as anode

Another name for the positive terminal in a voltaic cell

In a voltaic cell, the positive terminal is also known as cathode

Flow of current and flow of electron in a voltaic cell

The construction of chemical cell

A chemical cell can also be constructed by combining two half-cells with different E° values

A Daniell cell

Is an example of a voltaic cell where zinc, Zn metal and copper, Cu metal are used as electrodes, which are then dipped into their respective ionic salt solutions

A Daniell cell that uses a salt bridge

A Daniell cell that uses a porous pot
