Final answer:
The anion in hydrosulfuric acid is the hydrogen sulfate ion (HSO4-). The anion in hydrosulfuric acid is the sulfide ion, S2-, not sulfite, sulfate, or hydroxide as listed in the options.
Step-by-step explanation:
The anion in hydrosulfuric acid is the hydrogen sulfate ion (HSO4-). Sulfurous acid ionizes in two steps to form the first stage, the hydrogen sulfite ion (HSO3-), and the second stage, the sulfite ion (SO32-) (Ka1 = 1.2 × 10-2 and Ka2 = 6.2 × 10-9). Therefore, the correct option is not provided in the question.
However, the correct anion in hydrosulfuric acid is the hydrogen sulfate ion (HSO4-). The anion in hydrosulfuric acid is the hydrogen sulfate ion (HSO4-). The anion in hydrosulfuric acid is the sulfide ion, S2-, not sulfite, sulfate, or hydroxide as listed in the options.
