Question

what function does Zimmerman-reinhardt solution play in the estimation of iron with kmno4​

Answer 1

Answer:

Zimmermann-Reinhardtov reagens

Zimmermann-Reinhardt's reagent is a mixture of manganese(II) sulphate, sulphuric acid and phosphorus acid. It is used for preventing oxidation of chloride ion while titrating iron(II) ion with permanganate solution.

Answer 2

Zimmermann-Reinhardt's reagent is a combination of manganese(II) sulphate, sulphuric acid and phosphorus acid. It is borrowed for deterring the oxidation of chloride ions while titrating iron(II) ions with permanganate solution.

• In the lab necessary to perform a concurrent determination of iron(II) and iron (III) ions borrowing potassium permanganate solution.

• In the initial step, just fill up the provided sample solution to 100ml, take 20 ml of it and fill it into the flask. Then add 10ml of Reinhardt-Zimmermann-solution into the flask sample solution has hydrochloric acid in addition to iron (II) and iron (III)) and needs to titrate with KMnO4-solution (1/50M) until the solution in the flask shows an extremely faint pink colour.
