how do we find the oxidation state of N and P in ZnNH4PO4 since both N and P have more than one oxidation states?

answered-by-expert Expert Answer

This compound is a mixed salt of orthophosphoric acid, zinc and ammonium cation.

NH4+ is a derivative of ammonia NH3. Oxidation number of hydrogen is always 1 in compounds with nitrogen. Based on the fact that the molecule is electrically neutral, we get,

X + 3 = 0

X = -3

X - Oxidation number of N

The same principle defines oxidation number of Zn = 2, O = -2

-3 + 4 × 1 + 2  +  4 × (-2)  +  x = 0

X = 5

Answer: Oxidation number of N = -3, P= +5
