(a) Pt (s) |H₂ (g,0.1 bar) | |H⁺ (aq, 1M) | |Cu²⁺ (aq, 1M) | Cu
(b) Pt (s) |H₂ (g,1 bar) | |H⁺ (aq,1M) | |Cu²⁺ (aq, 2 M) | Cu
(c) Pt (s) |H₂ (g,1bar) | |H⁺ (aq,1M) | |Cu²⁺ (aq,1M) |Cu
(d) Pt (s) |H₂ (g,0.1bar) | |H⁺ (aq, 0.1M) | |Cu²⁺ (aq,1M) |Cu

c) Pt (s) |H₂ (g,1bar) | |H⁺ (aq,1M) | |Cu²⁺ (aq,1M) |Cu

Answer 2

Pt (s) |H₂ (g,1bar) | |H⁺ (aq,1M) | |Cu²⁺ (aq,1M) |Cu is the standard electrode potential of copper  electrode.

Explanation:

Standard electrode potential  

• It is used in electrochemistry.
• It is defined as standard state, the reversible electrode from an individual potential with ions will be measured at an effective concentration.
• The electric potential also differs from concentration, temperature, and pressure.
• The standard hydrogen electrode connects the copper electrode and measuring of standard electrode potential then cathode is acted.

                   Pt (s) |H₂ (g,1bar) | |H⁺ (aq,1M) | |Cu²⁺ (aq,1M) |Cu

• When coupling of standard hydrogen electrode, the pressure of H2 gas 1 bar and H+ ion is 1 molar.
• The concentration of reduced and oxidized form of order in the half cells right side was unique.
