## AhStlWt The dissociation constant of meta-arsenous acid (HAsO,) was accurately determined from spectrophotometric measurements, combined with volumetric methods. The measurement of pH of the analyte solution containing HAsO,, which was titrated with sodium hydroxide, was achieved by the spectro
Few studies of the abundance of arsenic in seawater have attempted to describe its distributiΒ°n between the arsenite and arsenate species' SΒ°rne recent investigatΒ°rs I 4 report measurable quantities of arsenite in seawater, although thermodynamically arsenate is by far the more stable form 5. Thus,
