Best ResponseYou've already chosen the best response.1This is a redox reaction... Write half reactions and balance them and add., Mn(7+)O4 +5e + 8H+ > Mn(2+) +4H2O .....*6 As(3+)2O3 +5H2O > 2As(6+)O4 +10H+ + 6e ...*5 Now add them to write the final equation... (I dont know how to use subscripts Sorry abt that).

Best ResponseYou've already chosen the best response.0You can also use the oxidationstate method it will be easier: 6KMnO4 +5 As2O3 +18 HCl + H2O > 6MnCl2 +10 H2AsO4 + 6KCl Mn(+7)+5eMn(+2) 6 As(+3)(3*2e)As(+6) 5

Best ResponseYou've already chosen the best response.1What i have done os the same thing you can't write Mn as 7+ directly as it is not an ion hence it should be written as MnO4

Best ResponseYou've already chosen the best response.0Why? u used method of half reactions but me the oxidationstate method ) i think both are correct

Best ResponseYou've already chosen the best response.1You can NOT write Mn as only Mn7+ in Mn04 in any method it is NOT an ion.

Best ResponseYou've already chosen the best response.0I know that it's not an ion.I balanced the atoms!!! At the result I obtained the correct answer) It's the main.
