Well, hello there, friend! Potassium permanganate (KMnO4) is often used as a secondary standard because it can be easily prepared to a high level of purity. Its rich purple color makes it easy to spot the endpoint of a titration, which is quite handy in the lab. Just like a happy little tree in a painting, KMnO4 brings a sense of reliability and consistency to chemical analysis.
The formula for potassium permanganate is KMnO4
The chemical formula for Condys Crystals is KMnO4, which stands for potassium permanganate.
K2CrO4 is a secondary standard. This is because it is not directly titrated against a primary standard but rather is standardized by titration against a primary standard, such as sodium thiosulfate in iodometric titrations.
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.
To find the mass of 2.55 mol of KMnO4, you can use the molar mass of KMnO4, which is approximately 158.034 g/mol. Multiply the molar mass by the number of moles: 158.034 g/mol * 2.55 mol = 402.84 g. Therefore, the mass of 2.55 mol of KMnO4 is 402.84 grams.
The formula for potassium permanganate is KMnO4
acidicness number of kmno4
KMnO4.
one is specific
tell me about the vlance of Mn in KMnO4
The chemical formula for Condys Crystals is KMnO4, which stands for potassium permanganate.
Potassium Hydroxide is KOH and potassium permanganate is KMnO4.
The compound potassium permanganate has chemical formula KMnO4 Molecular mass of KMnO4 = 39.1 + 54.9 + 4(16.0) = 158.0 Mass of KMnO4 = amount of KMnO4 x Molecular mass of KMnO4 = 2.55 x 158.0 = 403g

kmno4 is very good oxidizing agent. that means it is easily reduced by any other reagent. so it can't be considered as primary standard as its concentration changes upon free leaving
HSC is Higher Secondary Certificate which is 12th standard.....10th standard is called as SSC that is Senior Secondary Certificate.
