Find the oxidation number of sulphur in .

Answer»

mic molecules like have zero OXIDATION state. · The "oxidation number" of a "mono atomic" ion is EQUAL to the "ion's charge". · The "sum" of all "oxidation numbers" in a "neutral compound" is zero. · Alkaline METAL have +1 oxidation number and "alkaline earth metals" have +2 oxidation number. · Oxygen have  -2 oxidation state But the oxidation number of oxygen in peroxide form is -1.  · Oxidation number is Hydrogen is -1 but in binary metal HYDRIDE oxidation number of hydrogen is +1. · Oxidation number of halide are always -1, unless they are in combination with an oxygen or fluorine. Let the oxidation state of S be x. The oxidation state of oxygen is -2 Therefore, Therefore, the "oxidation state" of "sulphur" is +6
