what is the oxidation number for s in the compound so3? (recall that o has an oxidation number of -2.) 0 +2 +4 +6
Answer
Explanation:
Step1: Set up oxidation - number equation
Let the oxidation number of S be (x). In a neutral compound, the sum of oxidation numbers is 0. For (SO_3), there is 1 S atom and 3 O atoms. The oxidation number of O is - 2. So the equation is (x+3\times(-2)=0).
Step2: Solve the equation for (x)
[ \begin{align*} x - 6&=0\ x&=6 \end{align*} ]
Answer:
+6
