Question

What is the oxidation number of siin casio3

Answer 1

To calculate the oxidation uses the following rule as follows:

 

Total positive oxidation number + total negative oxidation number  

= net charge  

All elements have 0 oxidation stat.  

In this compound CaSiO3

The oxidation number of Ca= +2

Si =x

The oxidation number of O is -2

Therefore  

+2 + X (-2*3) =0

2 +  x -6= 0

x-4= 0

x= 4
