A wavelength of 540 nm is used for potassium permanganate (KMnO4) because it corresponds to the absorption maximum of the permanganate ion (MnO4-) in solution. At this specific wavelength, the absorbance is directly proportional to the concentration of permanganate ions, making it ideal for quantifying the amount of KMnO4 present in a sample.

What is the longest wavelength in nm that can dissociate a molecule of HI?
The longest wavelength that can dissociate a molecule of HI is determined by the ionization energy of the molecule. For HI, which has an ionization energy of 10.09 eV, the corresponding longest wavelength would be about 123 nm.
Why is 525nm the best choice to analyse potassium permanganate?
525nm is the best choice to analyze potassium permanganate because it is the wavelength where potassium permanganate has maximum absorbance, providing the most sensitive measurement. This wavelength allows for accurate determination of the concentration of potassium permanganate in a solution.
What does the nm stand for on a wavelength?
Well, darling, "nm" stands for nanometers. It's a unit of measurement used to quantify the wavelength of light. So, when you see "nm" on a wavelength, it's telling you the length of that wave in billionths of a meter.
A strong line in the spectrum of atomic mercury has a wavelength of 254 nm When mercury emits a photon of light at this wavelength the frequency of this light is?
To find the frequency of light emitted by mercury at a wavelength of 254 nm, you can use the formula: frequency = speed of light / wavelength. The speed of light is about 3.00 x 10^8 m/s. Convert the wavelength to meters (254 nm = 254 x 10^-9 m) and plug in the values to calculate the frequency.
What is the wavelength of chloride?
The wavelength of chloride is not a specific value, as chloride ions do not emit or absorb light in the visible spectrum. Chloride ions do not have a characteristic wavelength in the context of light.
What color has a wavelength of 540 nm?
A wavelength of 540 nm corresponds to the color green in the visible spectrum.
How do you calculate the wavelength of a red line at 670.8 nm?
670.8 nm is the wavelength.
What color has a wavelength of 530 nm?
A wavelength of 530 nm corresponds to green light.
The wave length is 670 nm what is the freguency of the radiation?
Use wavelength = frequency/300 000 with wavelength in metres and transpose.
What is the wavelength in nm of red light?
Red light typically has a wavelength of around 620-750 nm.
What color is light with a wavelength of 470 NM?
Light with a wavelength of 470 nm is in the blue part of the spectrum.
How hot is a metal being welded if it radiates most strongly at 540 nm?
The peak wavelength of 540 nm corresponds to a temperature of about 5300°C (9572°F) according to Wien's displacement law, which describes the relationship between an object's temperature and the wavelength at which it emits radiation most strongly. This indicates that the metal being welded is extremely hot, as welding typically occurs at temperatures above 2500°C (4500°F).
Radiation with a wavelength 4.2 nm?
X rays have a wavelength of 4.2 nm.
What is the wavelength of a photon whose energy is twice that of a photon with a 580 nm wavelength?
Since the energy of a photon is inversely proportional to its wavelength, for a photon with double the energy of a 580 nm photon, its wavelength would be half that of the 580 nm photon. Therefore, the wavelength of the photon with twice the energy would be 290 nm.
Why the lowry and biuret test use the different of distance waves?
The Lowry assay detects proteins by their aromatic amino acids absorbing light at a wavelength of 750 nm, while the Biuret test detects proteins by the presence of peptide bonds which absorb light at a wavelength of 540 nm. The different wavelengths are utilized based on the specific chemical properties of the substances being tested, allowing for accurate detection and quantification of proteins.
What is the typical wavelength of ultraviolet?
The typical wavelength of ultraviolet (UV) light ranges from 10 nm to 400 nm. UV light is further divided into UVA (315-400 nm), UVB (280-315 nm), and UVC (100-280 nm) based on its specific wavelength range.
What does nm in calculation of ultraviolet rays mean?
In the context of ultraviolet rays, nm stands for nanometers, which is a unit of measurement used to describe the wavelength of these rays. Ultraviolet radiation is classified into different categories based on their respective wavelength ranges, such as UVA (320-400 nm), UVB (280-320 nm), and UVC (100-280 nm).
