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.
What are some examples of concentrated solutions?
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 are 2 common oxidants and 2 common reductants?
Common reductants (substances readily oxidized) are the active metals, hydrogen, hydrogen sulphide, carbon, carbon monoxide and sulphurous acid.Common oxidants (substances readily reduced) include the halogens (especially fluorine and chlorine), nitric acid, oxygen, ozone, potassium dichromate, potassium permanganate, and concentrated sulfuric acid.Some substances are capable of acting either as reductants or as oxidants, e.g., hydrogen peroxide and nitrous acid.
How do you get iodine from iodide?
Use an Oxidizer, such as acidified Hydrogen peroxide, acidified Potassium permanganate, Sulfuric acid (concentrated), etc.
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?
Solid potassium permanganate with hydrogen peroxide produces more oxygen which is not united with other elements than solid potassium permanganate with sulfuric acid H2O2.
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 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.
Is it preferable to pour concentrated sodium hydroxide over sulfuric acid spilled on the floor?
No. The reaction of sodium hydroxide with sulfuric is more exothermic. And hence it is preferred to pour a solution of sodium bicarbonate or potassium bicarbonate in the case of spills.
What part of an experiment is food?
The highly concentrated sulfuric acid solution
Why is Concentrated sulfuric acid a weaker acid compared to dilute sulfuric acid?
Concentrated sulfuric acid has sulfuric acid molecules where dilute sulfuric acid has sulfate ions and hydrogen ions. Water in the diluted solution acts as the ionization medium.
