Which reaction produces more pure oxygen which is not united with other elements solid potassium permanganate with hydrogen peroxide or solid potassium permanganate with Sulfuric acid with H2O2?
The reaction that produces more pure oxygen which is not united with other elements is solid potassium permanganate with hydrogen peroxide rather than solid potassium permanganate with sulfuric acid with H2O2.

Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt
What is the importance of boiling KMnO4 solution if it is for future use?
If the potassium permanganate solution is prepared from stock solid potassium permanganate, it is important to remove manganese dioxide from the system. MnO2 catalytically decomposes permanganate into oxygen and lower ox. states manganese. Manganese dioxide is insoluble, whereas permanganate is very soluble. Boiling the solution would ensure that all solid permanganate had dissolved, and so little would be lost upon filtering out MnO2 (which remains insoluble at higher temperatures) The remaining solution will have a longer shelf-life due to the absence of the aforementioned decomposition catalyst. If the permanganate solution is required acidic, the use of a small amount of phosphoric acid can be effective. Typically, sulfuric acid is used in combination with permanganate as an acid oxidant. The problem being that sulfuric acid dissolves manganese and thus the catalyst becomes soluble, and difficult to remove. Stock acid solutions of permanganate have far reduced shelf-life. The addition of a small amount of phosphoric acid helps alleviate this. Manganese(ii) oxide reacts with acidified permanganate to form Manganese(iii) cations - these in turn precipitate from solution as manganese(iii)phosphate. Complex ions of manganese(iii) can also form with phosphate, and these partake roles in equilibrium resulting in their further deposition from solution. Once the phosphate complexes are removed by filtration of the hot acidified permanganate solution, the solution has a longer shelf-life.
How can cyclohexane be oxidized into cyclohexanone?
Cyclohexane can be oxidized into cyclohexanone by using an oxidizing agent such as potassium permanganate (KMnO4) or sodium dichromate (Na2Cr2O7) in the presence of a catalyst like sulfuric acid (H2SO4). The cyclohexane reacts with the oxidizing agent, resulting in the formation of cyclohexanol, which is further oxidized to cyclohexanone.
What is the name complex formed by the addition of concentrated sulfuric acid to carbohydrate solution and explain the reaction?
The complex formed by the addition of concentrated sulfuric acid to a carbohydrate solution is often referred to as a "carbohydrate-sulfuric acid complex." In this reaction, concentrated sulfuric acid dehydrates the carbohydrate, leading to the formation of carbon (often producing a black char) and water. The acid acts as a strong dehydrating agent, breaking down the carbohydrate structure and resulting in the release of water vapor and carbonaceous material. This reaction is typically exothermic and can produce significant heat.
Which reaction produces more pure oxygen which is not united with other elements solid potassium permanganate with hydrogen peroxide or solid potassium permanganate with Sulfuric acid with H2O2?
The reaction that produces more pure oxygen which is not united with other elements is solid potassium permanganate with hydrogen peroxide rather than solid potassium permanganate with sulfuric acid with H2O2.
Why does HCl not used to acidify the media in potassium permanganate titration?
HCl is not used to acidify the media in potassium permanganate titration because it can react with potassium permanganate, which can interfere with the titration results. Sulfuric acid is usually preferred as it does not react with potassium permanganate and ensures accurate titration results.
Which reaction produces more pure oxygen which is not united with other elements solid potassium permanganate with hydrogen peroxide solid potassium permanganate with Sulfuric acid with H2O2?
The reaction between solid potassium permanganate and hydrogen peroxide will produce more pure oxygen not united with other elements. This is because the reaction is more direct and doesn't involve the additional step of reacting with sulfuric acid.

What is the reaction between potassium permanganate and sulphuric acid and oxalic acid?
Potassium Permanganate (KMnO4) reacts with Sulphuric acid (H2SO4) to produce Manganese Heptoxide (MnO7), water (H20) and Potassium Hydrogen Sulphate (KHSO4)2. The reactive species produced is Manganese Heptoxide (which is a very powerful oxidiser). The Manganese Heptoxide will oxidise the Oxalic acid (COOH)2 to Carbon dioxide (CO2).
What part of an experiment is food?

Why does mixing alcohol sulfuric acid and potassium permanganate make a thunderstorm?
Concentrated sulfuric acid reacts with Potassium permanganate to produce manganese VII oxide (commonly called manganese heptoxide), Mn2O7. Mn2O7 is a very strong oxidizer and will rapidly react with most organic compounds even at room temperature. In this case the reaction is able to produce light and sound even without contact with oxygen gas.
How to prepare nitrate test solution using diphenylamine in sulphuric acid?
To prepare a nitrate test solution using diphenylamine in sulfuric acid, you can mix diphenylamine with concentrated sulfuric acid in a specific ratio. Typically, a 0.1% diphenylamine solution in concentrated sulfuric acid is used for nitrate testing. Follow safety precautions when working with concentrated sulfuric acid as it is corrosive.
