Question

find the oxidation number of NaH2PO4

Answer 1

$\Huge\bigstar\:\tt\underline\red{:ANSWER:}$

$\pink\longmapsto\:$ $\huge\mathbb$Na H2 po4.

$\large\mathscr\red{Sodium}$$\large\mathscr\orange{hydrogen}$$\large\mathscr\purple{Phosphate}$.

• $\huge\mathbf\red{ Na= +1}$.
• $\huge\mathbf\pink{H=+1}$.
• $\huge\mathbf\green{o=-2}$.
• $\huge\mathbf\orange{p=x}$.

• ${\implies}$${(+1×1)+(1×2)+x+(-2×4)=0}$
• ${\implies}$${+1+2+x+(-8)}$
• ${\implies}$${3+x-8=0}$.
• ${\implies}$${3+x=8=0}$.
• ${\implies}$${x=8-3=0}$.
• ${\implies}$${x=5}$.
