Guida verificata passo dopo passo1
Understand that the hydrogen sulfite ion is a polyatomic ion derived from sulfite (SO_3^{2-}) by adding one hydrogen ion (H^+).
Recall that adding a hydrogen ion to a polyatomic ion changes its formula by adding an H and reducing the negative charge by one.
Start with the sulfite ion, which is SO_3^{2-}, and add one hydrogen ion (H^+), resulting in HSO_3^-.
Verify that the charge on the hydrogen sulfite ion is -1, consistent with the addition of one H^+ to SO_3^{2-}.
Confirm that the correct formula for the hydrogen sulfite ion is HSO_3^- and not any other given options.
