Which metal acts as the cathode during silver plating?
Cathode, as the fork attracts silver cations (+ ions)
What instrument lead to the discovery of the neutron?
The Cathode Ray
What is true of both galvanic and electrolytic?
reduction happens at the cathode Oxidation happens at the anode
Why do the aluminum ions collect at negative electrodes?
Aluminium is formed at the cathode because the Al ions (Al3+) within the electrolyte are attracted to form aluminium metal by gaining 3 electrons. The metal is molten due to the high temperature of the cells. Hope this helps
What is true of both and electrolytic cells?
reduction happens at the cathode Oxidation happens at the anode
What happens in the cathode?
Metals ions form solid metal
What happens at the cathode in an electrolytic cell?
Reduction occurs at the cathode in an electrolytic cell.
What did experiments with cathode rays lead to the discovery of what?
experiments with cathode rays lead to the discovery of the Electron.
Which metal acts as the cathode during silver plating?
Cathode, as the fork attracts silver cations (+ ions)
What is true of both galvanic and electrolytic cells?
*electrolytic cells Oxidation occurs at the cathode
0n an LED what are the names of the positive and the negative leg?
Anode and cathode. Anode = negative lead, cathode = positive lead.
What happens in the cathode in an electrolytic cell?
Reduction occurs at the cathode in an electrolytic cell.
What is the sign convention for the cathode and anode in an electrolytic cell?
Anode is the positive electrode while cathode is the negative electrode. Negative ions(anions) travel towards the anode(hence the name) Positive ions(cations) travel towards the cathode(hence the name) Example for anode:Copper Example for cathode:Zinc
Do metals form at the anode or cathode?
Oxidation takes place at the anode and reduction takes place at the cathode, so elemental metal will form at the cathode, and elemental metal will form into ions at the anode.
Is the short lead the cathode on an led?
Yes
Did J J Thomson's experiments with cathode rays lead to the discovery of the neutron?
No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
What is the formula for the compound formed by lead ions and chromate ions?
Lead ions = Pb2+Chromate ions = CrO4-2Compound they form is Lead(II) chromate = PbCrO4
