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.
How do you prepare 500 mils 1 potassium hydroxide from N potassium hydroxide solution?
A mil is a measurement that equals one-thousandth of an inch, or 0.001 inch.
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 0.05 N solution of KMnO4?
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.
How do you Prepare 0.02 N potassium permanganate solution?
To prepare a 0.02 N potassium permanganate solution, you would need to dissolve 1.58 grams of potassium permanganate (KMnO4) in 1 liter of distilled water. This will give you a solution with a molarity of 0.02 N. Remember to wear appropriate personal protective equipment when handling potassium permanganate, as it can be harmful.

You have .2 n kmno4 which you have to dilute it to 0.05n kmno4 how can you dilute that?
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.
How will you prepare one liter of 0.1 N HCL solution from 12 N HCL?
To prepare 1 liter of 0.1N HCl solution from 12N HCl, you would need to dilute the 12N HCl by a factor of 120. To do this, you would add approximately 83.33 mL of 12N HCl to a container and then dilute it with water to reach a final volume of 1 liter. Make sure to mix the solution thoroughly after dilution.
How do you prepare 1 N ferrous ammonium sulphate?
To prepare 1 N ferrous ammonium sulfate solution, dissolve 392.15 g of the compound in distilled water and dilute to 1 L. This will yield a solution with a concentration of 1 N.
How do you prepare standard 0.1 N 100 ml Na2CO3 solution?
To prepare a 0.1 N 100 ml Na2CO3 solution, dissolve 5.3 grams of Na2CO3 in water and dilute to 100 ml. This will give you a solution with a concentration of 0.1 normal (N) for the 100 ml volume.
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.
How do you prepare 1 N sodium bicarbonate?
To prepare a 1 N solution of sodium bicarbonate, dissolve 84 grams of sodium bicarbonate in enough water to make 1 liter of solution. This will give you a 1 N (equivalent to 1 mol/L) concentration.
How prepare 0.1 N oxalic acid?
To prepare 0.1 N oxalic acid solution, you would need to dissolve 0.634 g of oxalic acid dihydrate (H2C2O4·2H2O) in distilled water and make up the solution to a final volume of 1 liter. This will give you a 0.1 N (normality) solution of oxalic acid.
How do you prepare 0.5 N acetic acid solution?
To prepare a 0.5 N acetic acid solution, first calculate the molarity needed using the formula Molarity (M) = Normality (N) x Equivalent weight. Then, use this information to dissolve the appropriate amount of acetic acid in water to make 1 liter of solution. Finally, adjust the volume with water as needed.
How do you prepare 0.1 N solution HCL from 1N?
Add 100 mL of HCl 1 N in a 1 L volumetric flask, class A or B; add ca. 850 mL distilled water to the flask. Place the flask in a thermostat at 20 0C. After 30 min add slowly distilled water to the mark (1 L) and stir well the closed flask. Pour the solution in a bottle. Place a label with the date, concentration, name of the solution on the bottle.
