Question:
How does the acidified \( KMnO_4 \) solution react with ferrous sulphate, \( SO_2 \), oxalic acid, and sodium thiosulphate?
How does the acidified \( KMnO_4 \) solution react with ferrous sulphate, \( SO_2 \), oxalic acid, and sodium thiosulphate?
Show Hint
Acidified \( KMnO_4 \) acts as an oxidizing agent, converting reducing agents into their oxidized forms while itself being reduced to \( Mn^{2+} \).

Solution and Explanation
Step 1: The acidified \( KMnO_4 \) acts as a strong oxidizing agent and reacts with various reducing agents.
Step 2: Reactions:
(i) With ferrous sulphate:
\[
2 KMnO_4 + 10 FeSO_4 + 8 H_2SO_4 \rightarrow 5 Fe_2(SO_4)_3 + 2 MnSO_4 + K_2SO_4 + 8 H_2O
\]
(ii) With \( SO_2 \):
\[
2 KMnO_4 + 5 SO_2 + 2 H_2O \rightarrow 2 MnSO_4 + K_2SO_4 + 2 H_2SO_4
\]
(iii) With oxalic acid:
\[
2 KMnO_4 + 5 (COOH)_2 + 3 H_2SO_4 \rightarrow 2 MnSO_4 + 10 CO_2 + 8 H_2O + K_2SO_4
\]
(iv) With sodium thiosulphate:
\[
2 KMnO_4 + 5 Na_2S_2O_3 + 6 H_2SO_4 \rightarrow 2 MnSO_4 + 5 Na_2SO_4 + 3 S + K_2SO_4 + 3 H_2O
\]
