tell me about the vlance of Mn in KMnO4
Potassium Hydroxide is KOH and potassium permanganate is KMnO4.
In potassium permanganate (KMnO4), the manganese (Mn) atom is in the +7 oxidation state, leading to its electron configuration of [Ar] 3d^0 4s^0. Since there are no electrons in the 3d or 4s orbitals, there are no unpaired electrons in KMnO4. Therefore, KMnO4 has zero unpaired electrons.
MnO2: oxidation number +4KMnO4: oxidation number +7
When KMnO4 is added to ethanol, it gets reduced to MnO2, causing the initial color change. However, when excess KMnO4 is added, MnO2 gets further oxidized back to KMnO4, resulting in the reappearance of the original color. This demonstrates the redox nature of the reaction between KMnO4 and ethanol.
The formula for potassium permanganate is KMnO4
KMnO4.

The chemical formula for Condys Crystals is KMnO4, which stands for potassium permanganate.
Potassium Hydroxide is KOH and potassium permanganate is KMnO4.
The compound potassium permanganate has chemical formula KMnO4 Molecular mass of KMnO4 = 39.1 + 54.9 + 4(16.0) = 158.0 Mass of KMnO4 = amount of KMnO4 x Molecular mass of KMnO4 = 2.55 x 158.0 = 403g
To dilute 0.2N KMnO4 to 0.05N KMnO4, you can add 4 times the volume of water to the original volume of KMnO4 solution. For example, if you have 100 mL of 0.2N KMnO4, you would add 400 mL of water to achieve a 0.05N KMnO4 solution. Mix thoroughly to ensure uniform dilution.
To find the mass of 2.55 mol of KMnO4, you can use the molar mass of KMnO4, which is approximately 158.034 g/mol. Multiply the molar mass by the number of moles: 158.034 g/mol * 2.55 mol = 402.84 g. Therefore, the mass of 2.55 mol of KMnO4 is 402.84 grams.
The purple KMnO4 is decolourise
The chemical formula for potassium permanganate is KMnO4.
No the purple solid KMnO4 is only very slightly soluble in the organic liquid cyclohexane.
Benzene cannot decolorize KMnO4 because it does not undergo addition reactions due to its stable aromatic structure. Alkenes, on the other hand, can decolorize KMnO4 because they can undergo addition reactions with KMnO4, breaking the double bond and forming a colorless product.
