Reversible electrodes with respect to hydrogen ion

Reversible electrodes with respect to hydrogen ion..A reversible hydrogen electrode (RHE) is a
Reference electrode
......A reversible hydrogen electrode (RHE) is a reference electrode, more specifically a subtype of the standard hydrogen electrodes, for electrochemical processes. Unlike the standard hydrogen electrode, its measured potential does change with the pH, so it can be directly used in the electrolyte.

1. Name: Mishuk Biswas Student electrode reversible with respect to h + ion

2. electrodes reversible with respect to h + ion R eversible hydrogen electrode Quinhydrone electrode Glass electrode Since  they act both anode as well as cathode , they are called reversible electrodes

3. reference electrode An electrode having an accurately maintained potential ; It is used as a reference for measurement by other electrodes. IDEAL REFERENCE ELECTRODE R eversible and obeys the Nernst equation Exhibits a potential that is constant with time Little hysteresis with temperature cycling

4. reversible hydrogen electrode A  reversible hydrogen electrode  ( RHE ) is a Reference electrode Since  it can act both anode as well as cathode , it is called a reversible electrode H + ( aq )+ ⇌ (g)  

5. standard hydrogen electrode Conditions Pressure : 1atm H + ion conc. : 1M Temperatur e: 25 o C Potential E = 0 volt .
