Question

2b.) Is the iron being oxidized or reduced in the reaction in question 1?


Question 1: Write a balanced net ionic equation for the reaction of Fe(NH4)2(SO4)2 X 6H2O with KMnO4 solution in aqueous acidic solution.


6.)In the following balanced equation, AB is the only colored species. All other species/reagents are colorless. If the goal of an experiment is the determination of the percentage of D in an impure sample of the salt, MD and the experiment technique to combine reagents for this determination is a titration, identify the reagent that will form the titrant? Justify your answer.


Equation: AB + D- > AD + B-




Explanation / Answer

Fe is presently in +2 state,so in this reaction it will get oxidised to +3 KMnO4 + Fe(NH4)2(SO4)2 = FeMnO4 + K(NH4)2(SO4)2 this is the balanced equation
