oxidation state of SO42-, NO2-, SiO32- and K2Cr2O7
2-
1-
2-
0
Explanation:
The oxidation states of the ions and compounds is given as;
SO₄²⁻ = 2-
NO₂⁻ = 1-
SiO₃²⁻ = 2-
K₂Cr₂O₇ = 0
Here are some rules that governs assignment of oxidation states;
1. For elements in uncombined states, the oxidation state is 0
2. For simple ions, the oxidation number is the actual charge carried.
3. The algebraic sum of all oxidation number of all atoms in a neutral compound is zero.
