Title: Balancing Redox Equations in Acidic or Basic Solutions? Post by: buffnstuff on Apr 21, 2012 MnO4- + SO3^2- +.... => MnO2 + SO4^2- + .....
What are the coefficients of the six species in the balanced equation above? Remember to include coefficients for H2O and OH- in the blanks where appropriate. Title: Balancing Redox Equations in Acidic or Basic Solutions? Post by: buffyoumofo on Apr 21, 2012 MnO4- + So3^2- = MnO2 + SO4^2-
2[3e- + 4H + MnO4- = MnO2 + 2H2O] 3[H2O + SO3^2- = SO4^2- + 2H + 2e-] TOTAL IONIC: 6e- + 8H + 2MnO4- +3H2O +3 SO3^2-= 2MnO2 + 4H2O + 3 SO2^2- + 6 H+ 6 e- NET IONIC: 2H + 2MnO4- + 3 SO3^2- = 2MnO2 + H2O + 3 SO2^2- :) Title: Balancing Redox Equations in Acidic or Basic Solutions?
