6.1-6.4: Electrolysis  

________ move to the positive electrode (anode) and each loses one electron to form bromine molecules.

________ is a rod of metal or graphite through which an electric current flows into or out of an electrolyte.

________ is a negatively charged ion which is attracted to the anode.

________ are non conductors because they contain no free electrons or charger particles that can flow through them.

________ is the ionic compound in molten or dissolved solution that conducts the electricity ⚡️.

If the metal is above hydrogen in reactivity series, then hydrogen will be produced and bubbling will be seen at the ________ (II) bromide.

________ is the negative electrode of an electrolysis cell.

________ is the positive electrode of an electrolysis cell.

________ is a positively charged ion which is attracted to the cathode.

If the ________ is above hydrogen in the reactivity series, then hydrogen will be produced and bubbling will be seen at the cathode.

________ is the break down of an ionic compound when in molten or in aqueous form by the passage of electricity.

The halogen gases all produce their own colours (bromine is red- brown, chlorine is yellow- green and fluorine is paleyellow) ________.

________ dont conduct when solid but do conduct when melted or dissolved.

________ move to the negative electrode (cathode) and gain electrons to form a grey lead metal which deposits on the surface of the electrode.

Positively charged H+ and ________ are attracted to the negative electrode but only one will gain electrons.

If a dilute ________ is being electrolysed, oxygen is formed.

Positive is ________ is Cathode.

If no ________ are present, then OH- is discharged at the anode, gains electrons and forms oxygen gas.

________ (other than hydrogen) are attracted to the positive electrode.

________ in the solid state can not conduct electricity either since they have no free ions or electrons that can move and carry charge.

________ can not conduct electricity hence they do not undergo electrolysis.
