Alkaline solutions of tantalum (V) have been studied by spectrophotometric, emf, and light scattering techniques. The position of the charge transfer band at about 2000 A did not change as the total tantalum concentration or the hydroxide ion concentration were varied. The emf measurements indicated that the compound K{sub 8}Ta{sub 6}O{sub 19} {center_dot} 16H{sub 2}O dissolves in dilute KOH solutions without appreciable protonation. The scattering of potassium 12-tungstosilicate was also studied as a check. Comparisons are made with structures for other poly-cations and anions which are found at high concentrations in monodisperse systems.
