What is the equation for the reaction with ammonium iron(II) sulphate, dilute sulphuric acid and potassium permanganate?
140408

All you need are the two ionic half-equations:
 
Oxidation: Fe2+(aq) -> Fe3+(aq) + e-
 
Reduction: MnO4-(aq) + 8H+(aq) + 5e- -> Mn2+(aq) + 4H2O(l)
 
Combining these two half-reactions, so that the loss and gain of electrons cancels out, gives the balanced ionic equation for the reaction.
 

 

 

Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website. For further guidance see our tutorial on Risk Assessment.
