Determination of the stability constant for an iron (iii) sulfosalicylate complex

Written by Dan Abstract The stoichiometry of the major complex formed was determined to have a 1:1 ratio of iron (iii) and sulfosalicylate acid using the continuous variation method. The stability constant for the formation of the complex was then calculated using spectroscopic analysis and pH measurements to be 420.45 ± 6.18, which correlates closely to the literature value.   Figure 1 – sulfosalicylic acid Introduction Figure 2 – equilibrium for the deprotonation of the carboxylic acid group of sulfosalicylic […]
