Explain why platinums potential decreased

Reference no: EM13163941

A platinum electrode is immersed into an aqueous solution of 1M NaCl (pH=7) that issaturated with N2(g) at S.T.P. (i.e., 25°C, 1 atm).

The potential of the platinum electrode is measured as a function of time, starting from the moment of immersion.

The platinum's potential is found to decrease with time, reaching a steady-state value of -0.413 V vs SHE.

Explain why platinum's potential decreased with time and explain why the steady-state value was -0.413V vs SHE.
