What is the oxidation number of phosphorus (P) in phosphoric acid (H3PO4)?
Sedaia [141]

Hey there!:

H is always +1 so the H's have a +3 charge.

O is always -2 so the O's have a -8 charge .

Now, suppose oxidation state for P = X , then :

+3  + X + (-8) = 0      (because of neutral molecule)

x = 8 - 3

x = + 5

So, X = +5 oxidation state.

Answer  C


Hope that helps!

Racemic mixture must have different melting point in comparison to the pure enantiomers.

considering a racemic mixture, individual enantiometer possesses a greater affinity for its kind of molecules than for those of the other enantiometer
