| Description |
The present work has been conducted to elucidate on the cathodic reactions in neutral alkali and alkalineearth
metal chloride solutions. The experiments were carried out on platinum anode in neutral chloride solutions
of sodium, potassium, magnesium, strontium, and barium (electrolyte for chlorate process) by means of steadystate
E-log i curves. The results indicate that the cathodic hydrogen evolutions in sodium and potassium
chloride electrolyte yield similar curves. The cathodic hydrogen evolution reaction in magnesium, strontium,
and barium chloride electrolytes takes place at more negative potentials (about 120-150 mv) than that in
sodium and potassium chloride. This is due to the difference in local pH and hydroxide precipitation near the
cathode surface. The hydroxide precipitation on the cathode surface in the case of alkaline earth metal salts
was overcome by the rotation of cathode at 1.38 m s-1.
