How many grams of potassium permanganate are in 2.20 moles?

To calculate the grams of potassium permanganate in 2.20 moles, you would need to know the molar mass of potassium permanganate. The molar mass of potassium permanganate (KMnO4) is about 158.034 g/mol. So, 2.20 moles of KMnO4 is equal to 2.20 moles x 158.034 g/mol = 347.67 grams of potassium permanganate.


What is maximum wavelength of absorbance of potassium permanganate?

The maximum wavelength of absorbance for potassium permanganate is around 525 nanometers. At this wavelength, potassium permanganate exhibits a strong absorption peak due to its characteristic deep purple color. This absorption peak is often used in spectrophotometric analyses to quantify the concentration of potassium permanganate in solution.


Is potassium permanganate and water solution or suspensions?

Potassium permanganate and water form a solution, unless here is so much potassium permanganate present compared to the amount of water that the solubility limit is exceeded. In the latter instance, there might be both solution and suspension.


Why does the purple colour spread when a crystal of potassium permanganate is placed in water?

The purple color spreads when a crystal of potassium permanganate is placed in water due to the dissolution of potassium permanganate molecules in water. Potassium permanganate is a highly soluble compound, and its purple color comes from the permanganate ions in the crystal dispersing in the water. This dispersion allows the purple color to be visible throughout the water.


Is potassium permanganate ionic or covalent?

Potassium permanganate is an ionic compound. It consists of potassium ions (K+) and permanganate ions (MnO4-), which are held together by ionic bonds formed through the transfer of electrons from potassium to permanganate ions.
