@The electrode labelled 'X' is connected to the positive terminal of a battery. The proper name for this electrode is:
#electro1
an anode
a cathode
an electrolyte

@Electrolytes are:
Liquids which allow electricity to flow through them
Solid substances that are conductors
The name given to charged particles in water

@The liquid in the water allows electricity to flow through it when X and Y are connected to a battery. The liquid is:
#electro1
an Electrolyte
a Conductor
a Cathode

@The electrode labelled 'Y' is connected to the negative terminal of a battery. This electrode is called:
#electro1
the cathode
the anode
an electrolyte

@The electrode labelled Y is the anode. This means it is connected to:
#electro1
A positive terminal on a battery
The negative terminal of a battery
Earth
