CONCLUSION

Sample Titration Practice 2 (Redox Titration)

You are provided with:

Acidified Potassium manganate(VII) solution A

• 0.1M of an iron (II)salt solution B
• 8.5g of ammonium iron(II)sulphate(VI) crystals (NH4)2SO4FeSO4.xH2O solid C

• Sample Titration Practice 2 (Redox Titration)

  You are required to

  (i)standardize acidified potassium manganaate(VII)

  (ii)determine the value of x in the formular (NH4)2SO4FeSO4.xH2O.

  Procedure 1

  Fill the burette with solution A. Pipette 25.0cm3 of solution B into a conical flask. Titrate solution A with solution B until a pink colour just appears. Record your results to complete  table 1.
