Related Question AnswersHow do you write chromium III sulfate?
Since Cr(III) has a valence of 3 and the sulfate radical SO4 has a valence of 2, then you need 2 x Cr and 3 x SO4 to equal the 6 valence ties. Therefore, CR(III) sulfate is Cr2(SO4)3.

How do you get the oxidation number?
Explanation:- The oxidation number of a free element is always 0.
- The oxidation number of a monatomic ion equals the charge of the ion.
- The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements.
- The oxidation number of O in compounds is usually -2, but it is -1 in peroxides.
What is the charge of so4?
Sulphate anion has -2 charge or it can be said that net oxidation no of the ion is -2. Oxidation no of oxygen is normaly -2 barring some exceptions of peroxides and super oxides. Sulphur is having oxidation state of +6 because it shares six valance electrons.What is the oxidation state of so4?
