What is the oxidation state of each element in the compound caso4? include + or - in your answers as appropriate. the oxidation state of calcium is . the oxidation state of sulfur is . the oxidation state of oxygen is .

- Ca = +2, S = +6 and O = -2

Solution:- There are certain rules for oxidation numbers. As per the rule, oxidation number of alkaline earth metals in their compounds is +2.

Oxidation number of oxygen in it's compounds is -2(except peroxides) and the sum of oxidation numbers of all the elements of a neutral compound is zero.

Since, Ca is +2 and O is -2, the oxidation number of S could easily be calculated for the given compound as:

Let's say the oxidation number of S in is . Let's make the algebraic equation and solve it.

Hence. the oxidation number of Ca is +2, O is -2 and S is +6.
