Question

\[ S_2O_3^{2-}(aq) + OH^{-}(aq) \rightarrow SO_4^{2-}(aq) + H_2O(l) + e^{-} \]  
After the above half reaction is balanced, which of the following are the coefficients of \(OH^{-}\) and \(SO_4^{2-}\) respectively?

• A. \(8,\;3\)
• B. \(6,\;2\)
• C. \(10,\;2\)
• D. \(5,\;2\) \bigskip

Hint:

In basic medium, balance oxygen with \(H_2O\), hydrogen with \(OH^{-}\), and finally balance charge using electrons.
