Dissolve 31,6 g KMnO4 in 1 kg acidified distilled water.
By solving 100 mg of KMnO4 in 1 L of distilled water at 20 0C.
Dissolve 1,58 g KMnO4 for analysis in 1 L distilled water at 20 oC.
700gram = 0.7 kilogram
First we look at the equation involving KMnO4 in Redox reaction. MnO4- + 8H+ + 5e- -------> Mn2+ + 4H2O Hence 5 electrons are transferred in the reaction. Therefore 1N solution of KMnO4 = M/5 solution of KMnO4 i.e., 0.20M KMnO4 solution. Hence 0.1N KMNO4 solution is equivalent to 0.02M KMnO4 i.e., a solution containing 3.1607g/L of KMnO4
there is tow method to prepare 1n kmno4 it's depend on oxidation number. Iknow one of this method you need 31.6 gms in one L D.WATER IF YOU KNOW FURTHER INFORMATION PLEASE TELL ME.
To prepare 2L of a 5M solution, you should put in 4.6575grams of KMnO4. It is important to make sure that you add them in that order. K should be added first, then Mn.
Dissolve 0,1 g of potassium permanganate in 100mL water.
1 mole KMnO4 = 149.032g KMnO4 2.55mol KMnO4 x 149.032g KMnO4/mol KMnO4 = 380.0316g KMnO4 = 3.80 x 102g KMnO4, rounded to three significant figures.
acidicness number of kmno4
Dissolve 1,65 g potassium permanganate for analysis in 1 L demineralized water.
