Calculate the oxidation number of the underlined element in the following ions. ul(S)_(2)O_(3)^(2-) |
|
Answer» Solution :`S_(2)O_(3)^(2-)` : Let the oxidation number of each S atom in this ion be X. The SUM of oxidation NUMBERS of all the atoms PRESENT must be equal to the CHARGE present on this ion i.e., equal to -2. Therefore, `(x)xx2+(-2)xx3=-2` or 2x=-2+6 or `x=(-2+6)/(2)=+2` Hence, the oxidation number of S in `S_(2)O_(3)` ion is +2. |
