DeFord and Hume's method is used to calculate the stepwise formation constants, the reduction is found to be quasireversible and diffusion controlled involving three electrons in each case. The constant ionic strength (µ=1M) has been maintained using KNO3 as a supporting electrolyte. Gelling's method was used to calculate Er1/2 values for As(III) complexes. The complexes with metal to ligand ratio as 1;1, 1:2, 1:3 have been reported. The stability constants have been also calculated by Mihailov's method for As(III)-Glycine system at 304K for different percentages of 1-Propanol and Ethanol (20%, 40% and 60%). https://journalofchemistry.org/paper/711/ Glycine 1-Propanol Ethanol polarographic study quasireversible dropping mercury electrode
