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

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. Electrolysis is this process of using an electric current to bring about chemical change in an electrolyte; it is not simply a physical separation of the ions.

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

Name the elemental product correctly: bromide ions form bromine, Br₂, at the anode.

Explain anode replacement as a reaction: oxygen produced at the anode reacts with its carbon to form carbon dioxide.

The positive electrode in electrolysis, which attracts negative ions.

The positively charged electrode in an electrolytic cell, which attracts anions.

The electrode connected to the negative terminal is the cathode, and the electrode connected to the positive terminal is the anode. Then use the ion's charge to determine its direction of migration: cations to the cathode and anions to the anode.

The positive electrode in an electrolytic cell, where negative ions or electrode atoms lose electrons.

The positive electrode in an electrolytic cell, where oxidation occurs.

The positive electrode in an electrolytic cell, where oxidation takes place.

The positive electrode in an electrolytic cell, where anions lose electrons; non-metals can form there when inert electrodes are used.

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 positive electrode during electrolysis, where negative ions lose electrons.

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

The positive electrode in an electrolysis cell, where negative ions or other species lose electrons.

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

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

Anions move towards the positive anode.

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

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

The positively charged electrode in electrolysis, where negative ions lose electrons.

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

The positive electrode in electrolysis, where particles lose electrons.

The positive electrode in electrolysis, where oxidation occurs.

The positive electrode in electrolysis, where particles lose electrons and oxidation occurs.
