Consider an electrochemical cell based on the reaction: 2H⁺ (aq)+ Sn (s)→ Sn²⁺ (aq)+ H₂ (g) Which of the following actions would change the measured cell potential? A)increasing the pH in the cathode compartment B)lowering the pH in the cathode compartment C)increasing the [Sn²⁺] in the anode compartment D)increasing the pressure of hydrogen gas in the cathode compartment E)Any of the above will change the measure cell potential.

Question

Quizplus · Accepted Answer

The cell potential is influenced by the concentration of reactants and products (as per the Nernst equation), pH changes (which affect the concentration of H+ ions), and gas pressure (for reactions involving gases). Thus, all the given actions would change the measured cell potential.
