source of the iron(II) ion, and potassium permanganate, KMnO4, will be the source of the permanganate ion. A. Preparation of the standard 0.01 M KMnO4 solution: Prepare an approximately 0.01 M KMnO4 solution by weighing, to four significant figures, enough solid KMnO4 salt to prepare 250 mL of solution. Weigh the KMnO4
by permanganate ion so the oxalate can be titrated directly. However, oxalate ions react only slowly with permanganate ions at room temperature so the solution must be warmed to about 60 ºC in order for the reaction to be fast enough to be useful in a titration. Objectives 1. to practice skills required for quantitative volumetric analysis.

In other words, a titrant volume of 75.0 mL is used. At this point we assume that all iodide is initially as insoluble AgI salt. The total silver ion added to the solution is . The amount of excess silver ion is the that amount added, less the amount reacted. The total solution volume is volume is 25.0 mL sample + 75.0 mL titrant = 100.0 mL.

Introduction Iron tablets contain iron(II) sulfate which is a soluble inexpensive form of 'iron supplement'. The experiment is to determine the percentage by mass of iron(II) sulfate in each tablet. Iron(II) ions can be oxidised to iron(III) ions by potassium manganate(VII) in acidic solution. In acidic conditions the deep purple solution of manganate(VII) ions is…
Potassium chromate can serve as an end point indicator for the argentometric determination of chloride, bromide and cyanide ions by reacting with silver ions to form a brick-red silver chromate precipitate in the equivalence point region. The Mohr method uses chromate ions as an indicator in the titration of chloride ions with a
