Except for a few metal ions, most notably UO2+, most inorganic ions are not sufficiently fluorescent for a direct analysis. Many metal ions may be determined indirectly by reacting with an organic ligand to form a fluorescent, or less commonly, … Continue reading →
An alternative to the method of continuous variations for determining the stoichiometry of metal-ligand complexes is the mole-ratio method in which the amount of one reactant, usually the moles of metal, is held constant, while the amount of the other reactant … Continue reading →
The method of continuous variations, also called Job’s method, is used to determine the stoichiometry of a metal-ligand complex. In this method we prepare a series of solutions such that the total moles of metal and ligand, ntotal, in each … Continue reading →
Structures of (a) EDTA, in its fully deprotonated form, and (b) in a six-coordinate metal–EDTA complex with a divalent metal ion.
Illustration showing the solubility of AgCl, SAgCl, as a function of pCl. The dashed red line shows SAgCl if one assumes incorrectly that the only relevant reaction is AgCl(s) ↔ Ag+(aq) + Cl–(aq) The solid blue curve is the actual solubility when considering … Continue reading →
