Question

Br2 + NaoH=NaBrO3+NaBr+H2O balanced by oxidation number method​

Answer 1

Answer:

Explanation:

first find oxidation number

oxidation number of br in nabro3 = 5

oxidation number of br in nabr = 1

now inter change oxidation numbers with other atom

when balancing any reactions water should be removed

br2 + naoh = nabro3 + 5nabr

now balance by ooc method

balance na first

br2+6naoh =nabro3 + 5nabr

now balance br

3br2 + 6naoh = nabro3 + 5nabr

now balance oxygen by water

3br2 + 6naoh = nabro3 + 5nabr + 3h2o

Answer 2

Explanation:

first find oxidation number

oxidation number of br in nabro3 = 5

oxidation number of br in nabr = 1

now inter change oxidation numbers with other atom

when balancing any reactions water should be removed

br2 + naoh = nabro3 + 5nabr

now balance by ooc method

balance na first

br2+6naoh =nabro3 + 5nabr

now balance br

3br2 + 6naoh = nabro3 + 5nabr

now balance oxygen by water

3br2 + 6naoh = nabro3 + 5nabr + 3h2o
