What happens when potassium reacts with Sulphur dioxide?
Here, S is in +4 oxidation state. Hence, SO2 has both oxidizing and reducing character. K is a stronger reducing agent and hence, it will reduce SO2.
Does Koh react with SO2?
At lower temperature, the dominant reaction between KOH and SO2 produces K2-SO3 and H2O. Any H2O remaining on the surface is converted into H2SO4 as SO2 and O2 are introduced. Then, the KOH and SO2 reaction produces K2SO4 and H2O.
What happens when you mix sulfur and potassium nitrate?
Charcoal, Potassium Nitrate and Sulfur react together to give Potassium Carbonate, Potassium Sulfate, Potassium Sulfide, Carbon Dioxide, Carbon Monoxide, Water and Nitrogen.
Does KMnO4 react with SO2?
Sulfur dioxide reacts with potassium permanganate (SO2 + KMnO4) This reaction is a redox (oxidation-reduction) reaction as the reactant’s oxidation number changes after products being produced. Therefore, it is a redox reaction where SO2 acts as the reductant and KMnO4 acts as the oxidant.
What kind of oxide is Sulphur dioxide?
It is an acidic oxide and dissolves in H2O to form H2SO4.
What happens when Sulphur dioxide gas is passed through acidified potassium permanganate solution?
Sulphur dioxide being a strong reducing agent ,reduces the purple coloured solution to form a colourless solution . …
Is Sulphur dioxide a Vapour?

What is potassium nitrate and sulfur used for?
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer.
What happens if you mix vinegar with potassium nitrate?
This reaction happens spontaneously and without warning. Mixing these two will form a corrosive, toxic chemical known as peracetic acid.
What happens when SO2 is passed through KMnO4?
Which Sulphur dioxide Decolourises acidified KMnO4?
SO2– decolurises Acidified KMnO4. The pink colour of KMnO4 is (reduced) decolourised by SO2- gas as follows. Even hydrogen sulphide (H2S) reduces and decolourises Acidified KMnO4 as follows.
