NaH4PO2   (if there is no net charge of the compund)
FOR Na we have +1 o.s, for H +1, for O we have -2
so total
+1+4(1)+x+2(-2)= 0
1+4+x-4=0
x= -1
rate

Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

i guess its  NaH (sodium hydride) + H3PO2 (Hypophosphorous acid)  = NaH4PO2 , so the oxidation state of phosphorus must be 5 as in HPA.

4+x-4=-1
=> x= -1
