SUMMARY
The discussion centers on the search for a molar absorptivity database for potassium permanganate specifically at 410 nm in relation to Beer-Lambert Law. It is established that molar absorptivity values are typically tabulated at the wavelength of maximum absorbance, which for potassium permanganate is around 425 nm. Users may not find reliable data for 410 nm due to its position on a steep edge of a strong absorption band, necessitating personal measurement and calculation for accurate results.
