Tron(11) ion salts, such as FeSO, 7H,O, react with the organic compound ortho-phenanthroline (phen) to form red coordination compounds with formulas such as Fe(phen),SO4. Such compounds have an analytical wavelength of 510 nm. (1) A standard solution containing Fe(phen),SO, was made by dissolving 0.0139 g of FeSO4 · H20, with a molar mass of 278.05 g mol-1 in 500.0 mL of water containing excess phen. The solution has a %T of 36.5% at 510 nm. A 500.0-mL solution with unknown Fe(phen),,SO4 concentration has a %T of 64.3% at 510 nm.
