What else can I help you with?
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.
Is KMnO4 soluble or not soluble is cyclohexane?
No the purple solid KMnO4 is only very slightly soluble in the organic liquid cyclohexane.
Which meniscus is to be seen in the burette containing kmno4 solution and why?
In the burette containing KMnO4 solution, the concave meniscus is observed. This is because KMnO4 is a colored solution that has strong adhesive forces with the glass walls of the burette. As a result, the liquid molecules are more attracted to the glass, causing the meniscus to curve downward.
What happen when ethanol is heated with alkaline kmno4 solution?
When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen. KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process. however. when all of the ethanol has been oxidised into ethanoic acid, and we keep adding Kmno4, the colour returns, as there is no more ethanol left to oxidise.
What colour change occurs when h2o2 is added to kmno4?
When hydrogen peroxide (H2O2) is added to potassium permanganate (KMnO4), the purple color of KMnO4 solution fades, turning into a colorless solution. This color change indicates the reduction of KMnO4 to Mn2+ ions.

What is molarity of a solution that contains 0.798 g KMnO4 in 50.0 mL solution?
The molar mass of KMnO4 is 158,3415 g.The molarity of this solution is 0,1 M.
What happens when ethanol is oxidised with acidified kmno4 solution?
When ethanol is oxidized with acidified KMnO4 solution, it undergoes complete oxidation to form ethanoic acid (acetic acid). The purple KMnO4 solution is reduced to green Mn2+ ions in the process.
How much grams of kmno4 to prepare 1000 ppm solution?
To prepare a 1000 ppm (parts per million) solution of KMnO4 (potassium permanganate), you need 1000 mg of KMnO4 per liter of solution. Since 1 gram equals 1000 mg, you would need 1 gram of KMnO4 dissolved in enough water to make a final volume of 1 liter. Therefore, to prepare a 1000 ppm solution, dissolve 1 gram of KMnO4 in 1 liter of water.
Is KMnO4 soluble or not soluble is cyclohexane?
No the purple solid KMnO4 is only very slightly soluble in the organic liquid cyclohexane.

Which solution may be used to disinfect water?
a dilute aqueous solution of KMnO4 may be used.
How many 60 mg kmno4 tablets are needed to make following solution kmno4 1 5000 600 ml?

Does ethyne decolourize KMnO4 solution?
Yes it does. This is a general test for unsaturation.
How many moles of KMnO4 are present in 75.0 mL of a 0.0950 M solution?
Molarity = moles of solute/Liters of solution ( 75.0 ml = 0.075 Liters ) Algebraically manipulate, moles of solute = Liters of solution * Molarity Moles KMnO4 = (0.075 Liters)(0.0950 M) = 7.13 X 10 -3 moles KMnO4 ------------------------------------
