What happens after 5 minutes when you mix together potassium manganate with water?
When potassium manganate is mixed with water, it dissolves to form a purple solution. Over time, the solution may slowly turn colorless as the potassium manganate reacts with water and other substances present in the solution.
Why don't we use indicators in redox-titration?
Because the end point can easily be observed. Example: consider the titration between potassium manganate (IV) which is purple and ammonium iron (II) sulfate - colourless. At the end point the colourless standard solution will turn pale pink when the correct volume of deep purple titre is added. No indicator is required. Also this is not necessarily an acid base rxn
Why does acidified potassium permanganate turn from purple to colorless when added to an alkene?
When acidified potassium permanganate is added to an alkene, the purple color disappears due to the reduction of permanganate ions to colorless manganese dioxide. The alkene oxidizes the permanganate ions, causing them to be reduced and lose their color. This reaction is used to test for the presence of carbon-carbon double bonds in organic compounds.
When potassium iodide reactsa with potassium bromide in the presence of methylene what is the color change?
The reaction between potassium iodide and potassium bromide in the presence of methylene blue will result in the formation of elemental iodine (I2) which imparts a purple color to the solution. Initially, the reaction mixture will be colorless, but as iodine forms, the solution will turn purple.
What colour is PH paper when dipped in potassium hydroxide powder?
pH paper would go a deep purple in the presence of KOH (s) because it is a very strong alkali.
What happens after 5 minutes when you mix together potassium manganate with water?
When potassium manganate is mixed with water, it dissolves to form a purple solution. Over time, the solution may slowly turn colorless as the potassium manganate reacts with water and other substances present in the solution.
What is the test for unsaturation?
Add KMnO4 (Potassium Permanganate) which is a purple solution. If it is added to an alkene or alkyne it will turn colourless and produces a brown precipitate.
What is the colour of phenolphthalein in salt water?
It will turn purple
What happens when you heat potassium permanganate?
I'm not entirely sure but I'm pretty positive it turns black, thus releasing oxygen and this can be proved if the test tube containing the potassium manganate VII is connected to another test tube or bowl containig limewater because it will start to bubble and turn cloudy or milky.

What is in kno3 that makes fire turn into the color purple?
The element "Potassium" (K).
What color will potassium permanganate turn a potato?
dark brown...or really dark purple
Why does acidified potassium permanganate turn from purple to colorless when added to an alkene?

The alkene oxidizes the permanganate ions, causing them to be reduced and lose their color. This reaction is used to test for the presence of carbon-carbon double bonds in organic compounds.
Why does pattisum permangrate turn purple in water?
Potassium permanganate turns purple in water because it undergoes a reaction in the presence of water to form hydrated manganese dioxide, which is a purple compound. This change in color is due to the formation of the purple complex ion resulting from the reaction of potassium permanganate with water.
When potassium iodide reactsa with potassium bromide in the presence of methylene what is the color change?
The reaction between potassium iodide and potassium bromide in the presence of methylene blue will result in the formation of elemental iodine (I2) which imparts a purple color to the solution. Initially, the reaction mixture will be colorless, but as iodine forms, the solution will turn purple.
When the reaction with potassium had finished what would happen if you added universal indicator solution to the water?
If you add universal indicator solution to the water after the reaction with potassium, the indicator will change color depending on the pH of the solution. Potassium reacts with water to form potassium hydroxide, which is a strong base. The solution will likely turn purple or blue indicating a high pH.
How can you tell if a colourless liquid is an acid or an alkali?
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.
