Can you please help me answer the questions below?
Iron supplements contain soluble iron(II) salts to replenish them in the human body in case of deficiency. Iron is an essential mineral used in many functions, specifically in the transport of oxygen. Iron deficiency can occur through poor diet, or as a consequence of blood loss through menstruation or injury. There are two different ways the amount of iron(II) ion could be determined by titration. The iron tablet was placed in 250 mL beaker and dissolved and then that solution was placed in a burette. 25.00mL of a 0.0100 M solution was placed in an Erlenmeyer flask and titrated until the pink color disappeared. Finish the table below Is iron being oxidized or reduced? Why? Using the average volume in the table, the molarity of the KMnCU and the above equation, calculate the mg of iron (II) ion that was in the tablet.Explanation / Answer
3) iron is oxidised KMnO4 is reduced so as to have a redox couple.....or meq of KMnO4 and Fe2+ reacting in the flask will ne same...
or vol of KMnO4 X normality of KMnO4 = volume of Fe2+ X normality of Fe2+ (meq of the two)
normality of Fe2+ = (vol of KMnO4 X normality of KMnO4) / volume of Fe2+
normality of Fe2+ = 25 X (0.01 X 5)) / 28.2
= 0.0443 N
in case of Fe normality = molarity hence amount of Fe 2+ = 0.0443 M
sililarly by taking average ..... volume of average Fe2+ = 28 ml
or average Fe 2+ conc= (vol of KMnO4 X normality of KMnO4) / volume of Fe2+
= 25 X (0.01 X 5)) / 28
= 0.0446 M
