Answer to Problem 3STP
Correct Answer: Option (a)
Explanation of Solution
Reason for correct option: The given compound is
Thus, the oxidation number of Cu is +2.
Generally, the oxidation number of O is -2. Therefore, the oxidation number of S can be calculated as follows:
Let the value be x thus,
On calculating,
Thus, the oxidation number of S is +6.
Therefore, the oxidation number of Cu is +2, S is +6 and O is -2. The correct option is (a).
