Question
The oxidation state of Phosphorus (P) in Barium hypophosphite, $Ba(H_2PO_2)_2$ , is:
Answer: C
💡 Solution & Explanation
Barium is an alkaline earth metal with a fixed +2 state. Therefore, the hypophosphite ion is $H_2PO_2^-$ . Let the O.S. of P be x. $2(+1) + x + 2(-2) = -1 \Rightarrow x + 2 - 4 = -1 \Rightarrow x = +1$ .
