How to correctly use potassium permanganate, what is there

Made with potassium manganatePotassium permanganatePotassium permanganate is a strong oxidizing agent, and it is associated withReducing agentThe reaction will vary depending on the acidity of the solution. In an acidic solution, potassium permanganate reacts with potassium sulfite, and the product is manganese sulfate:

2kmNO4 5K2SO3 3H2SO42MNSO4 6K2SO4 3H2O are reacted in a neutral solution, and the product is manganese dioxide.

2kmNO4 3K2SO3 H2O2MNO2 3K2SO4 2KOH is reacted in an alkaline solution, and the product is potassium manganate:

2kmno4＋k2so3＋2koh2k2mno4＋k2so4＋h2o。

Potassium permanganateIt has strong oxidizing properties.

It is commonly used as an oxidant in laboratories and industries, and in case of ethanol.

i.e. decomposition. It will slowly decompose into manganese dioxide and potassium salts in acidic media.

and oxygen. Light has a catalytic effect on this decomposition, so it is often stored in brown bottles in the laboratory. As can be seen from the elemental potential diagram and the oxidation state diagram of the free energy, it is extremely oxidizing.

In alkaline solutions, its oxidation is not as strong as in acidic solutions. When used as an oxidant, its reduction products vary depending on the acidity and alkalinity of the medium.

Operators operating potassium permanganate must be specially trained, strictly abide by the operating procedures, stay away from fire and heat sources, and strictly prohibit smoking, eating and drinking in the workplace. The operating environment is closed and the ventilation is strengthened. Avoid dust generation.

Avoid contact with reducing agents and active metal powders. When handling, it is necessary to load and unload lightly to prevent damage to the packaging and containers. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment.

Empty containers may leave harmful substances behind.

In the past, my fish got white spot disease because of poor water quality, so I used potassium permanganate**theirs.

Strictly speaking, two parts per million (2ppm) of potassium permanganate is added to water and the diseased fish is soaked for 20-30 minutes. In fact, you don't have to be too strict when operating.

First of all, make about 1L of imitation water, if you add potassium permanganate, which is the size of a grain of rice like the previous millet, the water will turn dark red.

You can mix 1L of such a solution first, and then add it to your big fish pond and youqi is OK.

This amount does not need to be calculated too strictly, I have two fish tanks, one adds less of this aqueous solution (very little, colorless), and one adds more (light pink), the fish have been **successful, and now I am very happy.

Don't sprinkle potassium permanganate particles directly into it, it will hurt the fish a lot, and you will find them very excited to hide and dodge ......

Or, you can go to the place where the fish is sold, ask for the kind of solution that purifies the water, they have prepared it, and go back and add it according to the instructions. But I always think that thing has hormones, so it's better not to use it. Besides, it's suitable for a fish tank, how much do you have to use for such a big fish pond as ......

Other methods of purifying water, you can refer to the swimming pool, you can use alum, the landlord still remembers what he learned in high school chemistry class, and the gelatinous ......This method seems to be more suitable for your large fish pond.

The use of potassium permanganate includes seed disinfection, cataplexy control, virus disease control, downy mildew control, and wilt control.

1. Seed disinfection.

Before sowing, you can soak tomatoes, eggplants, peppers, cucumbers, watermelons and other vegetable seeds in a solution of 500 1000 times potassium permanganate for 15 to 20 minutes, which can kill fungi, viruses, bacteria and other germs on the surface of the seeds, and prevent the occurrence of diseases such as cataplexy and blight at the seedling stage of vegetables.

2. Prevention and treatment of cataplexy.

To prevent and control cucumber, pepper, tomato, eggplant and other vegetable seedling cataplexy, you can spray the seedbed with 500 1000 times potassium permanganate solution, spray once in 10 days, spray 2 3 times, can effectively prevent and control the occurrence of seedling cataplexy and blight.

3. Prevention and treatment of viral diseases.

Before the onset of tomato, pepper, zucchini, watermelon and other crop virus diseases, potassium permanganate 600 800 times liquid spray can be sprayed once every 7 10 days, and regular spraying can effectively prevent the occurrence of viral diseases.

4. Only prevent and control downy mildew.

Before or at the beginning of downy mildew in cucumbers, cabbage, spinach, lettuce and other vegetables, 600 800 times of potassium permanganate can be sprayed to prevent the occurrence of downy mildew, which is better than chlorothalonil.

5. Prevention and control of blight.

To prevent and control watermelon, celery socks and tomatoes, eggplants, peppers, cotton and other crops wilt, before sowing, potassium permanganate 500 1000 times liquid soaking for 8 10 hours, rinse with water after fishing, and then sow seeds; When planting, irrigate the roots with potassium permanganate 1000 times, before the onset of wilt, irrigate the roots with potassium permanganate 1000 times, irrigate once every 10 15 days, and irrigate 2 times 3 times, which can prevent the occurrence of blight, which is better than carbendazim and methyl tobuzin.

The guidelines for the proper use of potassium permanganate are as follows:

1. Closed operation and strengthened ventilation. Operators must be specially trained, strictly abide by the operating procedures, away from fire and heat sources, and smoking, eating and drinking are strictly prohibited in the workplace. Avoid dust generation.

2. Avoid contact with reducing agent and active metal powder. When handling, it is necessary to load and unload lightly to prevent damage to the packaging and the old waiter's noisy device. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may contain remorseful residues.
