How many grams of potassium permanganate KMnO4 are in 2.55 moles?
The compound potassium permanganate has chemical formula KMnO4 Molecular mass of KMnO4 = 39.1 + 54.9 + 4(16.0) = 158.0 Mass of KMnO4 = amount of KMnO4 x Molecular mass of KMnO4 = 2.55 x 158.0 = 403g
Can glycerin and potassium permanganate be found in products easlisly perchased at a drug store or any common store if so what name and use of each product?
Glycerol is the non-chemical name for glycerine. It's an over-the-counter gooey liquid you can get at most drug stores. Potassium permanganate is a very common pool fertilizer that you can purchase at some large 'mart' stores, and can always find at any pool store, in a black roughly powdered form. Glycerine is pretty safe. In fact, there are quite a few common uses for it, including soap, lotion, and even as a laxative. Potassium permanganate is a strong oxidizer, and therefore needs to be kept away from ignition sources. (Unless, of course, you're using it for one.)
What is the reaction of iron sulphate solution with potassium permanganate?
The Mn+7 ions (purple) are reduced to Mn+4 ions (brown), unless some diltue sulfuric acid has been added to the solution. This will make the Mn+7 ions reduce fully to Mn+2 ions (colourless). The end point of the reaction is gotton when there is a permanent pale pink tinge left in the conical flask. (The Potassium Permangante should be in a Burette and be released slowly into the flask containing the Iron Sulfate). HOWEVER: Iron sulfate gets oxidised by Oxygen in air and water and undergoes hydroylisis of water. Therefore you should use a primary standard like Ammonium Iron II sulfate for this reaction.
Why would you use sodium hydrogen carbonate and potassium hydroxide in a photosynthesis experiment?
Sodium hydrogen carbonate (baking soda) is used to provide carbon dioxide for photosynthesis, as it can release CO2 when mixed with water. Potassium hydroxide is used to absorb any excess carbon dioxide produced during the experiment, creating a controlled environment for studying the rate of photosynthesis.
What is the number of atoms for potassium iodide?
There is one atom of potassium in a unit of potassium iodide.
What is the formula of acidified potassium permanganate?
There is not one formula for acidified potassium permanganate, it is a mixture, not a pure compound. Next to water it contains: H+ and K+ and MnO4- Warning: Do NOT use hydrochloric acid to acidify!
How Potassium permanganate is use for purifying drinking water?
Potassium permanganate can be used for purifying drinking water by acting as a strong oxidizing agent to eliminate organic compounds, iron, and other impurities. By adding a small amount of potassium permanganate to water, it can help remove bacteria and odors, making the water safer to drink. However, it is important to use the correct dosage to avoid any negative health effects from excess intake of potassium permanganate.
Do you need soap to take a bath while you have chickenpox?
No, use potassium permanganate, and consult with a doctor.
Can you bathe a dog in Potassium permanganate?
No, you should not bathe a dog in potassium permanganate. It can be toxic if ingested or absorbed through the skin, and could cause irritation or other health issues for the dog. It is not safe to use for bathing pets.
What is a safe substitute for potassium permanganate?
A safe substitute for potassium permanganate is hydrogen peroxide. It can be used as an oxidizing agent in various applications, such as water treatment or as a disinfectant. Remember to always use caution and follow proper safety guidelines when handling chemicals.
Is there a substitute for potassium permanganate?
Hydrogen peroxide or chlorine dioxide can be used as substitutes for potassium permanganate in some applications. However, the effectiveness and specific use cases may vary, so it's important to consult with a professional or reference material before making a substitution.
Which of the following might you use to titrate an oxalic acid solution?
You could use a standardized solution of potassium permanganate (KMnO4) to titrate an oxalic acid solution. Potassium permanganate is a strong oxidizing agent that reacts with oxalic acid in an acidic medium, forming carbon dioxide gas, manganese dioxide, and water.
Why do not use Hcl instead of H2SO4 in preparation of potassium permanganate?
Hydrochloric acid (HCl) may react with the potassium permanganate produced, leading to undesirable side reactions. Sulfuric acid (H2SO4) is chosen because it is a non-oxidizing acid that maintains the stability and purity of the final product.
Why no use indicator in the standardizing potassium permanganate titration?
In the standardization of potassium permanganate titration, an indicator is not used because the titration is self-indicating. This means the solution being titrated changes color at the end point, so an additional indicator is not necessary. It is important to carefully observe the color change to ensure accurate titration results.
Why do we use a wavelength of 540 nm for KMNO4?
A wavelength of 540 nm is used for potassium permanganate (KMnO4) because it corresponds to the absorption maximum of the permanganate ion (MnO4-) in solution. At this specific wavelength, the absorbance is directly proportional to the concentration of permanganate ions, making it ideal for quantifying the amount of KMnO4 present in a sample.
Reaction of formaldehyde with potassium permanganate?
Benzaldehyde reacts with pottasium permanganate to generate benzoic acid (oxidation). Basic cnditions are required for the action of pottasium permanganate so sodium carbonate is used. But this gives sodium salt of benzoic acid which is soluble in water. To retrieve benzoic acid which is insoluble in water we use HCl.
How many grams of potassium permanganate KMnO4 are in 2.55 moles?
