Explanation of Solution
In
Here,
Therefore, the oxidation state of sulfur is +6.
The order is such that, initially oxidation is assigned O and H and with the help of oxidation states of O and H, the oxidation state of S is calculated.
(c)

Concept introduction: Oxidation state is the charge assigned to an atom in a compound. The oxidation-reduction reaction involves the gain and loss of electrons from atoms.
(c)
Answer to Problem 3RQ
In
Explanation of Solution
In
Calculation of the oxidation state of phosphorus is represented as follows:
Therefore oxidation state of phosphorus is +5.
The order of assigning oxidation state is as follows:
Na, H, O and P.
(d)
Interpretation: The oxidation state of each element in
Concept introduction: Oxidation state is the charge assigned to an atom in a compound. The oxidation-reduction reaction involves the gain and loss of electrons from atoms.
(d)
Answer to Problem 3RQ
The oxidation state of chlorine is -1 and chromium is +3.
Explanation of Solution
In
Therefore, the oxidation state of chromium is +3.
Thus, initially, the oxidation state of Cl is assigned and the oxidation state of Cr is calculated using Cl.
