In this research, the electrochemical reduction of hydrogen process
and the factors affecting the reduction potential have been studied
in this research. The effect of acid concentration on the shifting of
the volt-ampero-metric curves that expres
s the reduction process
and so its effect on both the reduction potential value of hydronium
ions on drop mercury electrode, and the speed value of reduction
reaction was studied. Then an amount of pyridine as organic
substance was added to a specific volume of acid in a specific
concentration to figure out the relationship between the amount of
pyridine added and the cathode current of the reaction to find out
the effect of added pyridine on the reaction speed and the
relationship between the amount of added pyridine and the
hydrogen reduction potential.
Pyridine was added to amount of acid to study the effect of
theaddition on the hydrogen reduction over potential.
