What is the oxidation state of an individual nitrogen atom in NH4OH?
A
+5
B
0
C
-3
D
+3
Verified step by step guidance1
Identify the molecular formula: NH4OH consists of an ammonium ion (NH4+) and a hydroxide ion (OH-).
Assign known oxidation states: Hydrogen (H) is usually +1, and oxygen (O) in hydroxide is usually -2.
Set up an equation for the ammonium ion (NH4+): Let the oxidation state of nitrogen be x. Since there are 4 hydrogens each with +1, the sum is x + 4(+1) = +1.
Solve for x in the ammonium ion: x + 4 = +1, so x = +1 - 4.
Confirm the oxidation state of nitrogen in NH4+ is -3, which is the oxidation state of nitrogen in NH4OH.
