Potassium permanganate and sulfite:
2MnO4-(aq) + 5SO32-(aq) + 6H+(aq) --> 5SO42- + 2Mn2+(aq) + 3H2O(l)
Note:
Potassium and sodium ions do NOT react, they are tribune-ions
Sodium sulfite is used to remove permanganate stains because it is a reducing agent that can effectively neutralize the oxidizing properties of permanganate. When sodium sulfite reacts with permanganate, it reduces it to colorless manganese dioxide, thereby removing the stain.
K2SO3 is the formula for Potassium Sulfite.
The concentration of the solution can be calculated by dividing the mass of the solute (12 grams) by the volume of the solution (3.3 mL) and converting to the appropriate units. This will give you the concentration of ammonium sulfite in grams per milliliter.
[2K+]tribunated + 2I-(aq) + Cu2+(aq) + [SO42-]tribunated --> --> CuI2(s) + [2K+ + SO42- ]tribunated
When ammonium sulfite is put in water, it dissolves and forms a solution. The solid compound will break apart into its ions, ammonium (NH4+) and sulfite (SO3^2-), which will be dispersed throughout the water. This process is a physical change, not a chemical reaction.
Sodium sulfite is used to remove permanganate stains because it is a reducing agent that can effectively neutralize the oxidizing properties of permanganate. When sodium sulfite reacts with permanganate, it reduces it to colorless manganese dioxide, thereby removing the stain.
the equation for this are? aldehyde + acidified potassium permanganate RCHO + 2KMnO4 + H2SO4 → RCOOH + K2SO4 + 2MnO2 ↓+ H20 aldehyde + Tollen's reagent RCHO + 2AgNO3 + 2NH4OH → RCOOH + 2Ag↓ + 2NH4NO3 +H2O aldehyde+ Fehling's reagent RCHO + 2CuSO4 + 4NaOH →RCOOH + Cu2O↓+ 2Na2SO4 + 2H2O THAT's ALL I KNOW aldehyde + Sodium Hydrogen Sulfite
K2SO3 is the formula for Potassium Sulfite.
The chemical formula of potassium sulfite is K2SO3.
The molecular formula for potassium sulfite is: K2SO3
Potassium sulfite is typically found in solid form as a white crystalline powder. It is not a gas or a liquid at room temperature. When dissolved in water, it forms an aqueous solution.
One way is to react hot aqeous solution of potassium hydroxide (KOH) with sulphur (S). The products will be K2S3, K2S2O3 (potassium thiosulphate) and H2O. Answer by aditya rajesh, 8th student at millennium school in dubai.
2MnO4- + 5H2O2 + 6H+ → 2Mn2+ + 5O2 + 8H2O Permanganate is added to H2SO4 + H2O2 and is reduced because it is a better oxidising agent that H2O2 the purple MnO4 ion is used up and the solution fades almost to clear if the mix is right
i think either potassium(II) sulfate or potassium sulfate
K2SO3 is the chemical formula for potassium sulfite. It is a white crystalline solid that is used as a reducing agent in chemical reactions. It can also be used as a preservative in food and beverage industries.
The name of K2SO3 is potassium sulfite.
