-To determine the concentration of potassium permanganate solution

-Purple coloured solution Potassium Permanganate will titrate with the solution of iron sulphate and the colour of iron sulphate will slowly turn pink as it reaches the end point.

-Colour change in colour in iron (ll) solution
-Amount of Potassium Permanganate used
-Mass of Iron (ll) sulphate
-Stated concentration of Potassium Permanganate in container


A) Preparation of Standard iron (ll) solution
• Pure hydrated iron(II) ammonium sulphate, Fe(NH4)2(SO4)2.6H2O
• Concentrated sulfuric acid
• Electronic balance
• 250 mL volumetric flask with stopper labels

B) Standardising Potassium Permanganate Solution
• standard iron (II) ammonium sulfate solution
• -potassium permanganate solution, KMnO4(aq)
• -2 mol/L sulfuric acid
• -50 mL burette
• -25 mL volumetric pipette
• -250 mL conical flask
• -10 mL measuring cylinder  retort stand and clamp

A) Preparation of standard iron (ll) solution
3g of hydrated iron (II) ammonium sulfate was weighted accurately, using a 50 mL beaker. The salt is transferred into a 250 mL volumetric flask using a filter funnel, washed down with distilled water. After that, 100 mL of water is added, followed by the addition of 5 mL CONCENTRATED H2SO4 into the volumetric flask. Lastly a stopper was used to close the volumetric flask and it’s then shake and made
