Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Identify the Reaction Type
The reaction involves arsenic(III) oxide reacting with hydrogen sulfide to form arsenic sulfide (\( As_2S_3 \)).
Step 2: Balancing the Reaction
\[ As_2O_3 + 3H_2S \rightarrow As_2S_3 + 3H_2O \] Here, arsenic oxide is reduced to arsenic sulfide while hydrogen sulfide is oxidized.
Final Answer: The sol formed in this reaction is arsenic sulfide (\( As_2S_3 \)).
