Which gas turns acidified potasium dichromate solution into green?
Sulfur dioxide gas turns acidified potassium dichromate solution green.
What happens when zinc is added to the acidified potassium permanganate?
When zinc is added to acidified potassium permanganate solution, zinc displaces manganese from permanganate ions. This reduction reaction causes the purple color of the potassium permanganate solution to fade as the manganese ions are formed. The resulting solution may turn colorless or pink, depending on the concentration of the reactants.
What compound will decolorize acidified potassium permanganate?
Hydrogen peroxide is a common compound that can decolorize acidified potassium permanganate solution as it undergoes oxidation by permanganate, causing the purple color to disappear.
Does carbon dioxide gas change acidified potassium dichromate solution green?
Yes, carbon dioxide gas will change acidified potassium dichromate solution from orange to green due to the reduction of the dichromate ion to chromium (III) ions in the presence of reducing agents like carbon dioxide.
What happens when zinc dust is added to an acidified solution of potassium permanganate?
When zinc dust is added to an acidified solution of potassium permanganate, a redox reaction takes place. The zinc reduces the permanganate ion, MnO4-, to form colorless manganese ions, while itself getting oxidized to zinc ions. The overall result is that the purple color of the permanganate solution fades as it is reduced.
What happens when ethanol is oxidised with acidified kmno4 solution?
When ethanol is oxidized with acidified KMnO4 solution, it undergoes complete oxidation to form ethanoic acid (acetic acid). The purple KMnO4 solution is reduced to green Mn2+ ions in the process.
What happens in a positive test for sulfur dioxide?
The aqueous acidified potassium dichromate(VI) solution turns from orange to green.
Which gas turns acidified potasium dichromate solution into green?
Sulfur dioxide gas turns acidified potassium dichromate solution green.

Which light yellow solution gives white precipitate with acidified silver nitrate?
The light yellow solution is likely to be sodium chromate. This solution would give a white precipitate of silver chromate when treated with acidified silver nitrate due to the formation of a sparingly soluble salt, Ag2CrO4.
What is the function of acidified cuso4?
Acidified CuSO4 is used as a reagent in the Fehling's test to detect the presence of reducing sugars in a solution. When a reducing sugar is present, it reduces the blue Cu2+ ions in the CuSO4 solution to red-brown Cu2O precipitate, indicating a positive result.
What compound will decolorize acidified potassium permanganate?
Hydrogen peroxide is a common compound that can decolorize acidified potassium permanganate solution as it undergoes oxidation by permanganate, causing the purple color to disappear.
What would you see when acidified silver nitrate solution is added to a solution of Low sodium salt?
When acidified silver nitrate solution is added to a solution of low sodium salt, it would form a white precipitate of silver chloride. This is due to the chloride ions in the low sodium salt reacting with the silver ions in the silver nitrate solution to form silver chloride, which is insoluble in water.
Does carbon dioxide gas change acidified potassium dichromate solution green?
Yes, carbon dioxide gas will change acidified potassium dichromate solution from orange to green due to the reduction of the dichromate ion to chromium (III) ions in the presence of reducing agents like carbon dioxide.

The zinc reduces the permanganate ion, MnO4-, to form colorless manganese ions, while itself getting oxidized to zinc ions. The overall result is that the purple color of the permanganate solution fades as it is reduced.
How Chlorobenzene give white precipitate on reaction with acidified silver nitrate solution this is correct or not?
Yes, this statement is correct. When chlorobenzene reacts with acidified silver nitrate solution, a white precipitate of silver chloride is formed due to the displacement reaction between the chloride ion from chlorobenzene and the silver ion from silver nitrate.
Why are oxidizing agents usually acidified before use?
Mr. Yahya Maharmeh says that the oxidizing agents such as potassium dichromate are acidified to keep the solution acidic, so to provide hydrogen ions since the reaction needs alot of protons
