Figure 12From: A Raman spectroscopic study of arsenite and thioarsenite species in aqueous solution at 25 °CDistribution of arsenite species as a function of pH at 25°C and 1 bar. Thermodynamic data used to contruct this diagram (pK1= 9.3; pK2= 12.1; pK3 = 13.4) are from Akinfiev et al.[8].Back to article page
