1. a) Define the following terms Standard solution.... Molar solution... b) A standard solution of a hydrated iron(II) salt, (NH4)2 Fe(SO4)2 n H₂O was prepared by dissolving 9.80g of the salt and making up to a 250cm solution in a volumetric flask. 25cm of this solution acidified required 26.5cm³ of a 0.02m Potassium permanate solution for complete reaction. MnO+5Fe +8H→ Mn+ SFe³ + 4H2O i. What is the name of the indicator used in this titration of Iron(II) salt with aqueous potassium permanga
