reaction is Na + Br ==. NaBr
for oxidation oxidation no of Na changes from 0 to +1 so Na is oxidised
half oxidation reaction is : Na === NaBr
for reduction Br2 === NaBr
on balancing these two half reaction we get
2Na + Br2 == 2NaBr
Sodium react with bromine to produce sodium bromide. Write out the oxidation half reaction for the...
