A solution contains 30 mg/L total arsenic as AS(III) (the arsenite system). The pH is 7.9 so the molar concentration of the arsenous acid (H3ASO3) specie is 10 times that of the dihydrogen arsenite (H2ASO3) specie and the remaining species of the arsenite system (HASO3- and AsO,³ are present in negligible abundances. The concentration of the arsenous acid specie in mg H3ASO3 per liter of solution would be most nearly

A solution contains 30 mg/L total arsenic as AS(III) (the arsenite system). The pH is 7.9 so the molar concentration of the arsenous acid (H3ASO3) specie is 10 times that of the dihydrogen arsenite (H2ASO3') specie and the remaining species of the arsenite system (HASO3- and AsOg,³ are present in negligible abundances. The concentration of the arsenous acid specie in mg H3ASO3 per liter of solution would be most nearly 27.27 4.582 45.82
