Recall the definitions of ions: a cation is a positively charged ion, and an anion is a negatively charged ion.
Identify the charge on the sulfur ion given in the problem, which is -2.
Since the sulfur ion has a negative charge, it means it has gained electrons.
Ions with negative charges are classified as anions because they carry a negative charge.
Therefore, a sulfur ion with a -2 charge is classified as an anion.
