A new electrochemical oscillation with a short period of 2 to 10 ms, named oscillation C, appears in H<SUB>2</SUB>O<SUB>2</SUB>-reduction reaction on a Pt electrode in H<SUB>2</SUB>SO<SUB>4</SUB> solutions when a small amount of chloride ions is added to the solution. It is suggested that oscillation C is caused by competition between H<SUB>2</SUB>O<SUB>2</SUB> reduction and chloride-ion adsorption, contrary to previously reported oscillations A and B which are caused by competition between H<SUB>2</SUB>O<SUB>2</SUB> reduction and H<SUP>+</SUP> reduction.
