Mno4- + So3-2 = Mno2 + sO4-2 (in neutral solution,but H+ ions will appear in the final question) solve this redox reaction and give me the method also

Thank you

1 answer

MnO4- + SO3-- >> MnO2 + SO4--

species before after gain
Mn 7 4 3 electr
O -2 -2 0
S 4 6 -2

therefore, we need 2 Mn for each 3 S

2MnO4- + 3SO3-- > 2MnO2 + 3SO4--
