The negative electrode in electrolysis, where positive ions gain electrons.

The cathode is the negative electrode, so it attracts positive ions. The anode is the positive electrode, so it attracts negative ions. At an electrode, an ion is discharged: it gains or loses electrons and reacts to form a product.

The negative electrode in electrolysis, which attracts positive ions.

The negatively charged electrode in an electrolytic cell, which attracts cations.

The electrode connected to the negative terminal is the cathode.

The negative electrode in an electrolytic cell, where positive ions gain electrons.

The negative electrode in an electrolytic cell, where reduction occurs.

The negative electrode in an electrolytic cell, where reduction takes place.

The negative electrode in electrolysis, where positive ions gain electrons and reduction occurs.

The negative electrode in an electrolytic cell, where cations gain electrons; metals or hydrogen can form there.

In an electrolytic cell, the cathode is negative and the anode is positive. An inert electrode, commonly graphite, conducts electricity but does not itself take part in the reactions.

The negative electrode during electrolysis, where positive ions gain electrons.

An electrode connected to the negative terminal of the power supply, where positive ions compete to form a product.

The negative electrode in an electrolysis cell, where positive ions gain electrons.

The negative electrode in an electrolytic cell, where positive ions gain electrons.

The negative electrode in electrolysis, where positive metal ions gain electrons.

When direct current passes through the molten compound, positive metal ions move towards the negative electrode, called the cathode. There they gain electrons and become neutral metal atoms. The electrical supply is therefore able to reverse the electron loss that occurred when the metal formed its compound.

The negative electrode during electrolysis, where positive ions gain electrons.

The negative electrode during electrolysis; positive ions move towards it and gain electrons.

The negative electrode in an electrolysis cell, where positive ions gain electrons.

The negatively charged electrode in electrolysis, where positive ions gain electrons.

The negative electrode in an electrolysis cell, towards which positive ions move.

In electrolysis, the cathode is negative and attracts positive ions; the anode is positive and attracts negative ions.

At the cathode, compare the metal with hydrogen in the reactivity series; at the anode, check for a halide ion.

Do not predict sodium metal from aqueous sodium chloride: hydrogen forms at the cathode.
