What is the standard electrode potential of Nitrate?
The standard electrode potential of nitrate (NO3-) is +0.96 V. This value is for the reduction half-reaction of nitrate to nitrite under standard conditions.
What do half reactions show?
They show the oxidation an reduction halves of a reaction
What are the half reaction for a galvanic cell with Ni and mg electrodes?
Ni2+(aq) + 2e- Ni(s) and Mg(s) Mg2+(aq) + 2e-
How can one determine the cell potential in a chemical reaction?
The cell potential in a chemical reaction can be determined by calculating the difference in standard electrode potentials of the two half-reactions involved in the cell. The cell potential is the difference between the reduction potentials of the two half-reactions. The formula for calculating cell potential is Ecell Ered(cathode) - Ered(anode).
Why hydrogen is used as a standard electrode?
Hydrogen is used as a standard electrode because it has a well-defined standard electrode potential and is easily reversible in its oxidation and reduction reactions. This makes it a reliable reference point for measuring the electrode potentials of other half-reactions in electrochemical cells.
Which electrode loses electrons and which half reaction occurs here?
The anode electrode loses loses electron and oxidation half reaction occurs at it.
How are standard electrode potentials determined for the half-cells listed in the Standard Reduction Potentials table?
Standard electrode potentials are determined through experiments where the half-cell reaction is coupled with a standard hydrogen electrode. By measuring the voltage generated, the standard electrode potential for the half-cell reaction can be calculated. The values in the Standard Reduction Potentials table are based on these experimental measurements.

What is the purpose of the reference electrode?
A reference electrode is an electrode with a well-known electrode potential. Its main function is to serve as a half cell to build an electrochemical cell.
What is half cell?
A half-cell is a structure that contains a conductive electrode and a surrounding conductive electrolyte.
What are the half reaction for a galvanic cell with Ni and mg electrodes?
Ni2+(aq) + 2e- Ni(s) and Mg(s) Mg2+(aq) + 2e-
What occurs at the cathode of a galvanic cell?
An oxidation half-reaction
What is the saturation point in an enzymatic reaction called?
The saturation point in an enzymatic reaction is called Vmax, which represents the maximum rate of reaction when all enzyme active sites are bound to substrate molecules. At Vmax, the enzyme is saturated with substrate and the rate of the reaction cannot increase further with an increase in substrate concentration.
What are the half reaction for an electrolytic cell with aluminum and gold electrodes?
Type your answer here... Al3+(aq) + 3e- Al(s) and Au(s) Au+(aq) + e-
