GENERAL KNOWLEDGE

Detailed explanation-1: -The cathode is a positively charged electrode. This is because the concentration of electrons is lower on the cathode. During the process of reduction, electrons are gained and cathode can gain electrons as it is positively charged. Thus, the cathode is the reducing electrode.

Detailed explanation-2: -Like an anode, a cathode is one of the electrodes in a battery as well. However, a cathode is referred to as the positive electrode because it gains electrons rather than loses them. Therefore, anodes oxidize (lose electrons) while cathodes reduce (gain electrons).

Detailed explanation-3: -Site of oxidation: electrons are lost by the metal. The anode is a reducing agent because its behaviour will reduce ions at the cathode. Mass decreases as the reacting anode material becomes aqueous. Site of reduction: electrons are gained by the ions around the cathode.

Detailed explanation-4: -The cathode is an electron donor and can cause reduction to occur. The negatively charged electrode will attract positive ions (cations) toward it from the solution. It can donate some of its excess electrons to such cations or to other species in the liquid being electrolyzed.

Detailed explanation-5: -When the circuit is closed (a wire connects the cathode and the anode) the electrons will be able to get to the cathode. In the picture above, the electrons go through the wire, lighting the light bulb along the way. This is one way of describing how electrical potential causes electrons to flow through the circuit.
