A study of 12-tungstosilicic and 12-molybdophosphoric acids in solution

A study of 12-tungstosilicic and 12-molybdophosphoric acids in solution

The behaviour of two heteropolyacids (HPAs) with quite different stability in aqueous solutions was systematically investigated by UV, IR and NMR spectroscopy and potentiometric titration. It was shown that the Keggin structure of 12-tungstosilicic acid (H4SiW12O40, WSiA) anion was sustained over a...
