What causes acidified potassium manganate Colourless?
This is a redox reaction. The permanganate ion (purple) is reduced to manganese(II) ion which is a very pale pink, or almost colourless. while sulfur dioxide is oxidized to the sulfate ion, which is colourless.
Is acidified potassium manganate an oxidising agent?
Potassium manganate(VII) is usually used in neutral or alkaline solution in organic chemistry. Acidified potassium manganate(VII) tends to be a rather destructively strong oxidising agent, breaking carbon-carbon bonds.
What happens when potassium permanganate reacts with hydrochloric acid?
Potassium permanganate reacts with hydrogen chloride to produce manganese (II) chloride, chlorine, potassium chloride, and water.
What is acidified potassium manganate test?
Using the reaction to test for carbon-carbon double bonds The situation with acidified potassium manganate(VII) solution is even worse because it has a tendency to break carbon-carbon bonds. It reacts destructively with a large number of organic compounds and is rarely used in organic chemistry.
What does acidified potassium dichromate test for?
Acidified potassium dichromate solution is an orange solution which changes to green when the alcohol is oxidised. This can be used as a test for alcohols and only alcohols will show the orange to green colour change with acidified potassium dichromate solution.
How do you test for an oxidising agent?
- Test for Oxidising Agent: Use of a Reducing Agent e.g. aqueous potassium iodide, KI(aq) Observation: Colourless solution turns brown.
- Test for Reducing Agent: Use of an Oxidising Agent e.g. acidified potassium manganate (VII)

What is in potassium permanganate?
What is potassium permanganate? Potassium permanganate is a common chemical compound that combines manganese oxide ore with potassium hydroxide. It was first developed as a disinfectant in 1857. Since then, it’s been widely used to treat a variety of skin conditions, including fungal infections.
