What Happens If Potassium Permanganate Is Consumed?

Ingestion of KMnO4 can cause damage to the upper gastrointestinal tract. Also it may cause systemic toxic effects such as adult respiratory distress syndrome, coagulopathy, hepatic-renal failure, pancreatitis, and even death in severe cases.

How to Prepare Potassium Permanganate Solution in Lab ?

Preparation of Potassium Permanganate – KMnO4 Potassium permanganate is commercially prepared by mixing solution of potassium hydroxide KOH and powdered manganese oxide MnO2, with oxidizing agents like potassium chlorate. The mixture is boiled and evaporates and the residue is heated in iron pans until it has acquired a pasty consistency. 6KOH + 3MnO2 + 6KClO3 → 3K2MnO9 + 6KCl + 3H2O The potassium manganate (green) formed is boiled with a large quantity of water and a current of chlorine, carbon dioxide CO2, and ozonized air is passed into the liquid until it is converted into permanganate. The MnO2 formed is removed continuously in order to prevent its breaking down. 6K2MnO4 + 3Cl2 → 6KMnO4 (Potassium Permanganate) + 6KCl The solution of KMnO4 is drawn off from any precipitate of MnO2 concentrated and crystallized. The crystals are centrifuged and dried.

Why do we standardize potassium permanganate?

The standardization of potassium permanganate used to determine the strength of potassium permanganate with a standard solution of oxalic acid. This reaction helps to study the oxidation and reduction theory.

Why KMnO4 is not used as primary standard?

KMnO4 is not used as primary standard because it is difficult to obtain the pure state of KMnO4 as it is not free from MnO2. Also, the color is so intense that it acts as its own indicator.
