Detailed Solution

The above statement is true.
Oxidation takes place at the anode. Because the anode(electrode) loses the electrons in a galvanic cell, it’s known as the negative electrode. When oxidation happens, electrons are left behind on the electrode.
In the anode(electrode), the metal atoms surrender their electrons to the metal and get into the solution. The electrons are left behind there, rendering it effectively negative, and also, the electron flow goes from it through the wire to the cathode.
Basically, oxidation means loss of electrons and it’s going to be possible if it happens at the anode as the anode is the electrode which is +vely charged, and so it must have lost electrons, and so it’s the positioning of oxidation.
The reduction is the gain of electrons, and it occurs at the cathode because the cathode is negatively charged, so it must have gained electrons and has the tendency to produce or lose electrons.
