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.
How many grams in 0.2N normality KMnO4 solution?
To find the grams of KMnO4 in a 0.2N solution, you need the equivalent weight of KMnO4, which is approximately 158.04 g/mol divided by 5 (since one mole of KMnO4 provides 5 equivalents for redox reactions). Therefore, the equivalent weight is about 31.61 g/equiv. For a 1-liter solution, 0.2N means there are 0.2 equivalents, which translates to about 6.32 grams of KMnO4 (0.2 eq × 31.61 g/equiv).
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.
Why does alkene reacts kmno4?
Alkenes react with potassium permanganate (KMnO4) through a process called oxidative cleavage, where the double bond is broken and oxygen atoms are added to the carbon atoms. This reaction results in the formation of diols (glycols) or ketones and carboxylic acids, depending on the conditions and the structure of the alkene.
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.
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.
Why is it permissible to use a wet bottle when first obtaining your KMnO4 solution?
It is permissible to use a wet bottle when first obtaining your KMnO4 solution because the potassium permanganate (KMnO4) is not affected by water and will still dissolve properly in the solution.
Why benzene cannot decolourize KMnO4 while alkenes can decolorize?
Benzene cannot decolorize KMnO4 because it does not undergo addition reactions due to its stable aromatic structure. Alkenes, on the other hand, can decolorize KMnO4 because they can undergo addition reactions with KMnO4, breaking the double bond and forming a colorless product.
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.

Is KMnO4 soluble or not soluble is cyclohexane?
No the purple solid KMnO4 is only very slightly soluble in the organic liquid cyclohexane.
What do you observe when ethyne is passed through ammoniacal cuprous chloride solution?
When ethyne is passed through ammoniacal cuprous chloride solution, the blue color of the cuprous chloride solution fades as the ethyne reduces cuprous chloride to copper, forming reddish-brown copper. This reaction is a test for unsaturation in organic compounds.
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.
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.
