(a) Write the net ionic equation for the reaction of aqueous iron (II) ion reacting with H2O2 in acidic medium.
(b) If hydroxide ion is formed, the OH- may react with some of the Fe3+ to produce an insoluble hydroxide. Will the percent yield of the iron (III) compound containing a complex ion be affected by the formation of the insoluble hydroxide?
(c) Write the balanced net ionic equation for the formtion of the insoluble hydroxide.
