Question

What is the oxidation number of $Si$ in the compound $CaSi{O}_3$?

• A. $-4$
• B. $+2$
• C. $-2$
• D. $+4$

Answer 1

The correct option is D $+4$

$CaSi{O}_3$

Total charge present $=0$.

Oxidation no. of Oxygen is $-2$.

Oxidation no. od Calcium is $+2.$

Let, oxidation no. of Slilicon be $X$.

So, $[+2]+x+3[-2]=02+x-6=0x=4$

So, oxidation number of silicon in $CaSi{O}_3$ is $+4$.
