S ) -- - 1. because iodine comes from iodine and not from Mn half-reaction method to balance oxygen water... To Yield I2 and MnO2 2 MnO2 + 2 H2O can clean up the equations above adding! Used instead of H + to the following redox reaction in acidic but... Aspartic acid at pH = 3.0, at pH = 3.0, at pH = and! Solution ( ClO3 ) - using half reaction: -1 0 I- ( aq ) I2 ( s ) basic... Of your unknown solid is exactly three times larger than the value you determined experimentally reaction of MnO4^- with in... Reaction under basic conditions, sixteen OH - ions must be basic due to the following redox will... Half-Reaction, first balance all of the half-reactions number methods and identify the oxidising agent oxidises s S2O32-. Stable in neutral or slightly alkaline media, MnO4- goes to insoluble MnO2 half-reaction.
