0.1 N KMnO4 refers to a solution of potassium permanganate (KMnO4) that has a normality of 0.1. Normality (N) is a measure of concentration equivalent to moles of solute per liter of solution, specifically tailored for reactions involving acids, bases, or redox processes. In this case, the 0.1 N value indicates that the solution contains 0.1 equivalents of KMnO4 per liter, which is commonly used in titrations and analytical chemistry for its oxidizing properties.

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.
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.

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 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.
To prepare a 0.05 N solution of KMnO4, you would need to weigh out the appropriate amount of KMnO4 based on its molar mass. Dissolve this calculated amount in a known volume of water, usually in a volumetric flask, and make up the volume to the desired final volume with more water. Thoroughly mix the solution to ensure uniform concentration.
