Standard Electrode Potentials. To measure the potential of the Cu/Cu 2 + couple, we can construct a galvanic cell analogous to the one shown in Figure \(\PageIndex{3}\) but containing a Cu/Cu 2 + couple in the sample compartment instead of Zn/Zn 2 +.When we close the circuit this time, the measured potential for the cell is negative (โ0.34 V) rather than positive.

The standard hydrogen electrode is a half-cell used as a reference electrode and consists of:. Hydrogen gas in equilibrium with H + ions of concentration 1.00 mol dm-3 (at 100 kPa); 2H + (aq) + 2e-โ H 2 (g). An inert platinum electrode that is in contact with the hydrogen gas and H + ions; When the standard hydrogen electrode is connected to another half-cell, the standard electrode.

Topological index (numeric number) is a mathematical coding of the molecular graphs that predicts the physicochemical, biological, toxicological, and structural properties of the chemical compounds that are directly associated with the molecular graphs. The Zagreb connection indices are one of the TIs of the molecular graphs depending upon the connection number (degree of vertices at distance.
