Title	: REDOX TITRATION I

Aim	: To determine the concentration of a solution of potassium permanganate

Apparatus : 
burette , pipette , funnel , conical flasks , 25 ml measuring cylinder , potassium 
permanganate solution , iron (II) sulphate , sulphuric acid , 

Directions : 
Pipette 25 ml of 0.01 molar iron (II) sulphate solution in a conical flask and add 10 ml of 0.1 molar sulphuric acid . Mix thoroughly . Titrate against a solution of potassium permanganate . Swirl the flask continuously until a faint permanent pink colour appears .

Questions  :
The equation for the reaction is as follows :

5iron(II) + manganate(VII) + 8Hydrogen ions --> manganese(II) + 5iron(III) + 4water

Calculate :
The number of moles of iron II in the titre volume .
The number of moles of permanganate that reacted .
The concentration of permanganate .

Why is the concentration of the acid not taken into consideration in the reaction ?
