The amount of manganese in steel is determined by changing it to permanganate io

Question

The amount of manganese in steel is determined by changing it to permanganate ion. The steel is first dissolved in nitric acid, producing Mn2+ ions. These ions are then oxidized to the deeply colored MnO4 ions by periodate ion (IO4T) in acid solution (a) Complete and balance an equation describing each of the above reactions. (Use the lowest possible coefficients. Include states-of-matter at 25°C and 1 atm in your answer.) dissolution of the steel chemPad Help Greek 3Mn Mn Your answer differs too much from the expected answer to provide useful feedback reaction with periodate ion in acid solution: chemPad Help Greek Your answer appears to be missing one or more states-of- matter

Explanation / Answer

a)

3Mn (s) + 2NO3- (l) + 8H+ (l) <===> 3Mn2+ (s) + 2NO (g) + 4H2O (l)

2NO (g) + 3S2O82- (l) + 4H2O (l) <===> 2NO3- (l) + 6SO42- (l) + 8H+ (l)

2Mn2+ (s) + 5IO4- (s) + 3H2O (l) <===> 2MnO4- (s) + 5IO3- (s) + 6H+ (l)
