Adverse Effects of KMnO4

Potassium permanganate is a sand-like substance that is odourless and dark purple in acidic, neutral, or weakly basic media. Potassium permanganate functions as a strong oxidising agent. Potassium permanganate, also known as Condy’s crystals or hypermangan, is an important disinfectant inorganic chemical. MnO4 is fused with alkali metal hydroxide (KOH) in the presence of oxygen or an oxidising agent such as KNO3. It creates K2MnO4, a dark green molecule. Normally, a concentrated potassium permanganate solution is corrosive and has a poisoning effect on health that can cause nausea and vomiting, shortness of breath, kidney failure and much more.

What Is Potassium Permanganate?

The chemical compound potassium permanganate comprises manganese oxide ore and potassium hydroxide. Its chemical formula is KMnO4. So, KMnO4 is a chemical compound with oxidising properties widely employed in various industries. 

Potassium permanganate was initially manufactured in the 1600s and was first used in medicine in the 1800s. It is listed as an essential medicine by the World Health Organisation. In 1857, it was initially used as a disinfectant. Since then, it’s been used to treat various skin diseases, including fungal diseases. Pemphigus, Impetigo, superficial wounds, dermatitis, and tropical ulcers are examples of fungal diseases of the foot. Now that you have become familiar with the basic concept of potassium permanganate. Let us understand the physical and chemical properties of potassium permanganate.

Physical And Chemical Properties Of KMnO4

Physical Properties

KMnO4 is a crystalline solid with a brilliant purple tint. It has an unscented density of 2.70 g/mL and a melting point of 240 degrees Celsius. It can be purchased as a powder, crystals, or tablets.

Chemical Properties

Potassium permanganate mixes quickly in water, resulting in a brilliant purple, dark pink, or magenta-coloured mixture due to the creation of a dark brown reduced derivative, MnO2, a strong oxidant that stains most organic materials (including skin and clothing) that come into contact with it. It is all you need to know about the physical and chemical properties.

Uses Of Potassium Permanganate

In water treatment

It destroys pollutants and eliminates unpleasant odours from water in water treatment facilities. Iron, hydrogen sulphide, and manganese are oxidised into solid particles and filtered out. Because the treatment produces no hazardous substances, it is quite safe.

In medical uses,

1. It is particularly effective in treating an athlete’s foot, a fungal infection. The fungus is killed by the oxidising action of permanganate solution, which relieves symptoms including itching and redness.
2. Permanganate of potassium is a disinfectant. It can be used as a disinfectant to treat skin infections such as dermatitis, canker sores, ulcers, eczema, and fungal infections because of its oxidising properties. When administered to minor wounds, it affects the microorganism’s outer cell membrane, oxidising and destroying its structure. But sometimes, its high concentration damages human health that induces shortness of breath, throat burning and much more.

Potassium Permanganate Hazards

• In many industries, KMnO4 is being handled carefully as it can cause severe damage to human health and the environment. Potassium Permanganate hazards are caused mainly when used in high doses, which is severely toxic, and its contact with the skin can cause irritation, redness, and even burns. High potassium permanganate concentrations in the stomach can induce abdominal pain, throat burning, shortness of breath, renal damage, and even death if swallowed.

• It can cause skin irritation. It is only recommended for use for a few days when treating eczema. Chemical burns can occur with higher concentration solutions. 

• It is not advised to use activated charcoal or drugs that cause vomiting. While drugs like ranitidine and N-acetylcysteine may be used to treat toxicity, little evidence supports their usage. 

• KMnO4 also affects kidneys and livers and might cause long term toxicity toward fertility or pregnancy. 

Conclusion

Therefore, we must use potassium permanganate in industries, medical usages, laboratories, and water treatment facilities according to a directed concentration provided by chemical scientists and engineers. As KMnO4 is a highly potent oxidising agent in the presence of dilute sulfuric acid, that’s why it is toxic. Potassium permanganate is a strong substance that needs to be diluted before being applied to the skin. It can harm your skin, mucus membranes of your nose, eyes, throat, anus, and genitals if it isn’t diluted. And can also damage your respiratory system. When preparing a dilution, always use gloves for extra protection.
