Molar extinction coefficient is depend on intensity of the colour of solution.If the solution has high intensity of colour, molar extinction coefficient is high.So when considering CoCl2 and KMnO4, CoCl2 has low colour intensity. KMnO4 solution has much intense purple colour.Therefore its Molar extinction coefficient is high.

What is the chemical formula for Condys Crystals?
The chemical formula for Condys Crystals is KMnO4, which stands for potassium permanganate.
What elements are in potassium permangante?
Potassium permanganate is composed of the elements potassium, manganese, and oxygen. Its chemical formula is KMnO4.
How many grams of potassium permanganate KMnO4 are in 2.55 moles?
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
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 the mass of 2.55 mol of KMnO4?
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.
What changes in color occur when bromine or KMnO4 reacts with an alkene?
The purple KMnO4 is decolourise
What is that chemical formula for potassium permanganate?
The chemical formula for potassium permanganate is KMnO4.
Why H2So4 is used in acidification of KMno4 solution not HCl or HNo3?
H2SO4 is used in acidification of KMnO4 solution because it is a stronger acid compared to HCl or HNO3, which ensures complete dissociation of the acid and provides a higher concentration of H+ ions for the redox reaction to occur efficiently. Additionally, H2SO4 is not easily oxidized by KMnO4, unlike HCl or HNO3 which could interfere with the redox reaction.
