What happens when potassium permanganate is standardized with ethanedioic acid?
When potassium permaganate is mixed with ethanedioc acid the potassium permanganate Mn04- ion will be converted toMn2+, this means that you will observe the purple colour changing to a clear solution and the permanganate ion is oxidised. The Mn2+ will act as an auto catalyst speeding up the reaction, therefore a funny rate will occur, where the reaction is slow to start, before speeding up and slowing down again at the end.

How long does potassium permanganate take to dissolve in water?
Potassium permanganate typically dissolves in water within a few minutes, as it is a highly water-soluble compound. Agitating the solution or using warm water can help speed up the dissolution process.
What is the amount percentage of manganese in potassium permanganate KMnO4?
% by mole. There are six elements in KMnO4 only one is K so 1/6 which is 16.67% % by mass. Molar weight of K 39grams/mole. Molar weight of KMNO4 154 grams/mole so 39/154 =25%
Sodium Peroxoborate reacts with sulfuric acid and potassium permanganate to give what products?
2MnO4- + 5H2O2 + 6H+ → 2Mn2+ + 5O2 + 8H2O Permanganate is added to H2SO4 + H2O2 and is reduced because it is a better oxidising agent that H2O2 the purple MnO4 ion is used up and the solution fades almost to clear if the mix is right
How do you clean up stains left by nail polish remover?
To clean up stains left by nail polish remover, first wipe the area with a damp cloth to remove any remaining residue. Then, use a mild detergent or soap with water to clean the stained area. For tougher stains, you can try using a mixture of baking soda and water to create a paste and gently scrub the stain before rinsing it off.
What makes up potassium permanganate?
Potassium permanganate is a compound made up of the elements potassium, manganese, and oxygen. Its chemical formula is KMnO4. It is a dark purple crystalline solid that is highly reactive and commonly used as an oxidizing agent in various chemical reactions.

Why does potassium permanganate dissolve quicker in hot water?
Potassium permanganate dissolves quicker in hot water because the increased temperature of the water speeds up the motion of the water molecules, allowing them to interact more effectively with the permanganate crystals. This increased kinetic energy helps break down the crystal lattice structure of the potassium permanganate, leading to faster dissolution.

How many grams of potassium permanganate contains 27.5 grams of oxygen?
This is more of a math question that requires a bit of knowledge of chemistry. So it helps to know the steps of this answer mathematically. Additionally it's worth noting that there are a number of ways to answer this question. The method I provide may take an extra step, but it allows for a better understanding of the process.First we need to know some basic information about potassium permanganate, KMnO4. This basic information can be found on a periodic table, like the one in the link below. The first step is finding the weight of oxygen in one mole of potassium permanganate as a percent. For this you need to know the atomic weights of the elements involved.K: 39.1 gramsMn: 54.9 gramsO: 16.0 grams × 4 atoms = 64.0 gramsKMnO4: 39.1 + 54.9 + 64.0 = 158.0 grams/molSo now we know the weight of one mole of potassium permanganate (158.0 grams). Because we also know the weight of oxygen, we can find the percent of oxygen in the compound by mass.64.0 grams O ÷ 158.0 grams KMnO4 = 0.405 = 40.5%In one mole of potassium permanganate, 64.0 grams of it is oxygen, meaning 40.5% of it is oxygen. Because of the Law of Definite Proportions, we know that in any amount of potassium permanganate, 40.5% of it is oxygen.Then you can set up an equation.40.5% of (some amount of KMnO4) = 27.5 grams oxygenLet's set the amount of KMnO4 as the variable "x".0.405x = 27.5x = 67.9 grams KMnO4
How does pulverizing speed up the rate of diffusion of potassium permanganate crystals?
Pulverizing increases the surface area of the potassium permanganate crystals, allowing more particles to come into contact with the surrounding medium. This increased surface area enhances the rate of diffusion because more particles are available to move from an area of high concentration to an area of low concentration.
How can one clean stains from the inside of coffee makers?
You can use glass cleaner to remove the stains that build up inside a coffee maker and to take away the stains. If dish soap does not work try a liquid cleanser with bleach which should definitely remove the stains.
What is the safest way to clean coffee stains from dentures?
The safest way to remove coffee stains from dentures is by using a product like polydent. You can pick it up at you local drug store.
