Manganese sulfate has an ionic bond.
Since NaOH is easily water-soluble, complete dissociation will occur, and you will only have ions. Adding manganese ions (in the form of either manganese chloride or manganese nitrate) will give you the net ionic equation Mn+2(aq) + 2OH-(aq) --> Mn(OH)2(s).
When phenol reacts with potassium permanganate in an acidic medium, the purple permanganate solution turns colorless as it is reduced to manganese dioxide. This reaction is a redox reaction where phenol is oxidized to benzoquinone.
When manganese(II) nitrate solution is mixed with sodium hydroxide solution, a white precipitate of manganese(II) hydroxide is formed. The balanced chemical equation for this reaction is: Mn(NO3)2 + 2NaOH → Mn(OH)2 + 2NaNO3
Ethanol (CH3CH2OHl) + KMnO4 ----> Ethanal (CH3CHO) -----> Ethanoic Acid (CH3COOH) Primary Alcohol Oxidized ---> Aldehyde Oxidized---> Carboxyilic Acid You could attain Ethanal by using the oxidizing agent Pyridinium Chlorochromate (PCC) anhydrously.
Manganese dioxide is insoluble in water.

Yes, manganese has ions in solutions.
Manganese carbonate is typically produced through the reaction of manganese oxide or manganese sulfate with sodium carbonate or sodium bicarbonate in a controlled aqueous environment. The process involves mixing the reactants in solution, followed by precipitation, where manganese ions combine with carbonate ions to form manganese carbonate. The precipitate is then filtered, washed, and dried to obtain the final product. Additionally, it can be synthesized using carbonation techniques involving carbon dioxide gas in a suitable solution.
Adding a DNS (dinitrosalicylic acid) solution stops enzymatic catalyzed reactions by denaturing the enzymes involved, preventing them from further catalyzing reactions. DNS reacts with reducing sugars produced by the enzyme-catalyzed reaction, forming a colored product that can be measured to determine the amount of sugar present at the time of stopping the reaction.
.45% saline solution. It is a hypotonic solution.
A reducing sugar such as glucose can be oxidized by both Benedicts solution and Tollens reagent to form a colored precipitate. This reaction is used to test for the presence of reducing sugars in a solution.
Toxic cyanide is oxidized to cyanate (OCN−) that is not toxic..
Dissolve a known amount of potassium permanganate in a known volume of demineralized water; calculate the concentration of manganese in the solution.
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.
