Formation constants of alkaline-earth metal complexes with semi-xylenol orange and semi-methylthymol blue.
Potentiometric and spectrophotometric studies on the interactions of Semi-Xylenol Orange and Semi-Methylthymol Blue and alkaline-earth metal ions are reported. Two complex species, MHL(-) and ML(2-), for each indicator and element have been found to be formed in aqueous solutions, and the formation constants and the arrangements of these complexes have been determined.
