To prepare a 120 N (normal) solution of potassium permanganate (KMnO4), you need to calculate the required mass based on the desired volume of the solution. The normality (N) refers to the number of equivalents per liter; for KMnO4, one equivalent corresponds to one mole since it acts as a strong oxidizing agent. First, determine the molar mass of KMnO4 (approximately 158.04 g/mol), then calculate the mass needed using the formula: mass (g) = normality (N) × equivalent weight (g/equiv) × volume (L). Finally, dissolve the calculated mass of KMnO4 in distilled water to achieve the final volume.

What is 0.1 N kmno4?
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.

What is the Normality of H3PO4 solution contains 275g H3PO4 in 120 L of solution?
Calculus with (units) in brackets shows the way how and why.275 (g) / 97.9 (g/mol) = 2.81 mol in 120 L = 2.81 (mol) / 120 (L) = 2.34*10-2 (mol/L) = 0.0234 M H3PO4And since there are 3 protons available per mole: 0.0234 (M) H3PO4 * 3(N/M) = 0.0702 N

How do you prepare the 1N concentration of potassium permamganate solution?
N (normality) describes a solution that contains 1 gram equivalent weight (gEW) per liter solution. An equivalent weight is equal to the molecular weight divided by the valence (here it gets a little tricky, for acids ands bases it refers to the number of H+ or OH-, in salts it must be expressed which ion is meant unless the ratio is 1:1). In the case of KMnO4, equivalent wt is reaction specific. When KMnO4 is used in acid medium as oxidiser, 5 electrons are gained by Mn atom. So equivalent wt of KMnO4 in acid medium = Molecular wt/no.of electrons gained in redox reaction = 158/5 =31.6. So for 0.1N KMnO4 solution, you have to dissolve 3.16g KMnO4 in 1L water. (Usually a little bit excess is taken, say 3.25g, since some crystals of KMnO4 will be remained undissolved that have to be removed by filtration. So eventhough u r preparing 0.1N KMnO4 solution by accurate weighing,it is not a primary standard and u have to standardise it against a primary std such as oxalic acid or sodium oxalate. In alkaline or neutral medium, reaction of KMnO4 is different and Mn gains 3 electrons in redox reaction. So, for alkaline medium redox titrations, equivalent wt of KMnO4 will be 158/3 = 52.6. So for 0.1N KMnO4 solution in alkaline medium redox titration, dissolve 5.26g in 1L water.
