measurements of low carbon steel (0.05% C) as well as weight-loss measurements
at different pH values ranging from 1 to 4 in solutions of different
concentrations of two inhibitors sodium sulphite and hydrazine have been
investigated in presence of chloroacetic acid solutions. The steady state
potential shifted to more positive values by increasing pH from 1-2 while
the corrosion potential increased to more negative values at pH 3-4. The
corrosion rate increases with decrease in concentration of sulphite and
hydrazine.</span
