Prof. Clark Walter · Accepted Answer

The correct answer is d. Sn(s) | Sn²⁺(aq) ∥ H⁺(aq) | H₂(g) | PtExplanation:The half reactions are: 2H⁺(aq) + 2 e- ⟶ H₂(g) (reduction)Sn(s) ⟶ Sn²⁺(aq) + 2 e-  (oxidation)In the cell notation, there are two electrodes in which are separated the reduction reaction from the oxidation reaction. In the left electrode occurs the oxidation reaction (anode) while in the right electrode occurs the reduction reaction (cathode). The general form of the cell notation is the following:anode reaction∥ cathode reactionwhere the two bars ( ∥ ) represent the physical barrier between the electrodes. A single bar ( | ) is used to represent a phase separation.   In this redox reaction, the half reaction of the anode is Sn(s) ⟶ Sn²⁺(aq) + 2 e-; whereas the half reaction of the cathode is 2H⁺(aq) + 2 e- ⟶ H₂(g).The componens are written in order according to the half reaction. Since Sn²⁺ and H⁺ ions are in solution, a platinum electrode is used and represented as Pt. Thus, the cell notation is: Sn(s) | Sn²⁺(aq) ∥ H⁺(aq) | H₂(g) | Pt

The cell notation for the given cell will be:  Explanation:For the given cell reaction:The half cell reaction follows:Oxidation half reaction:  Reduction half reaction:  Oxidation reaction always occurs at anode.Cell notation is the representation in which, the anode is written on left hand side followed by its ion with its molar concentration. It is then followed by a salt bridge, which is represented by the symbol "||" . Then the cathodic ion with its molar concentration is written and then the cathode.Hence, the cell notation for the given cell will be:
