Understand the concept of 'thio': In chemistry, the prefix 'thio-' indicates the replacement of an oxygen atom with a sulfur atom in a compound.
Identify the original formula: The sulfate ion is represented as \( \text{SO}_4^{2-} \).
Apply the 'thio' concept: Replace one oxygen atom in the sulfate ion with a sulfur atom. This changes the formula from \( \text{SO}_4^{2-} \) to \( \text{S}_2\text{O}_3^{2-} \).
Verify the charge: The charge of the thiosulfate ion remains \( 2- \) because the replacement of an oxygen atom with a sulfur atom does not affect the overall charge of the ion.
Review the options: Compare the derived formula \( \text{S}_2\text{O}_3^{2-} \) with the given options to confirm the correct answer.
