Find the oxidation number of sodiumNa inNaCl.
Step-1 Calculating the charge on NaCl
Step-2 Calculating the oxidation number of Na inNaCl-:
FormalChargeonNaCl=OxidationnumberofNa+OxidationnumberofCl
0=x+-1
0=x−1
x=+1
Hence, the oxidation number of Sodium Na in NaCl is +1
Find the oxidation state of sodium in Na2O2.
