An electrochemical cell possesses cathode and anode. A cathode is a metal electrode which is responsible for reduction (gain of electrons). An anode is a metal electrode which is responsible for oxidation (loss of electrons).The reaction happening in left hand side solution is as follows: Ti3+aq + 3e- → Tis The reaction happening in right hand side solution is as follows: Cr2+aq → Cr3+aq + e- It can be seen that left hand side solution shows reduction (gain of electrons) and right hand side solution shows oxidation (loss of electron). Reduction happens at cathode and oxidation happens at anode. Thus, cathode is made up of thalium (Tl) which is present at left electrode and anode is made of platinum (Pt) which is present at right electrode. Answer: Tl / Pt
