Because Potasium dichromate (Potassium Dichromate solvated in dilute (0.001N) perchlorate acid) gives absorption at two characteristics wavelength at 235nm to 350nm ( for 20mg/L to 100mg/L) and 430nm (for 600mg/L) that's why used in wide range for linerity test of spectrophotometer.

Why potassium chloride used for calibration of limit of stray light in UV?
Cuz we dont know
Why you are using kcl in the calibration of uv visible spectrophotometer?
how do you determine degree of deacetylation of chitosan using UV -vis spectrophotometer
What is the percentage of UV rays that hit the earth?
about 7% of the UV rays hit the earth.
What is oxygen cycle?
The continual interchange of oxygen between the atmosphere and the water, the plants and animals and mineral matter is called the oxygen cycle.
Which layer of earth's atmosphere contains a gas that absorbs ultraviolet radiation?
All parts of the atmosphere contain gases that absorb UV-B and more energetic radiation. All parts of our atmosphere pass UV-A.
Why Potassium dichromate is used for calibrate the control of absorbance of UV spectrophotometer?
Potassium dichromate is used as the primary standard for UV spectrophotometry because of its properties. It is pure, stable, has no waters of hydration, and has a high molar mass.

Why1.2 percent water solution of potassium chloride used in UV calibration?
The solution of potassium chloride is used to evaluate the stray light.
Why you use holmium filter for UV calibration?
to check the sensitivity of the instrument

Why do you use 0.005M h2so4 solution for preparation of k2cr2o7 solution for UV calibration?
A 0.005M H2SO4 solution is used to prepare a K2Cr2O7 solution for UV calibration because it provides an acidic medium, which helps stabilize the dichromate Cr(VI) ions in the K2Cr2O7 solution. This stability ensures consistent and accurate UV calibration readings. Additionally, the specific concentration of H2SO4 is chosen to maintain a controlled environment for the reaction and analysis process.
Why limit of stray light perform in uv calibration and how?
Limit of stray light is important in UV calibration to ensure accurate measurements by reducing interference from unwanted light. This is typically done by using optical components that block or absorb stray light, such as filters or baffles. By minimizing stray light, the calibration process can be more precise and reliable.
Why is Erbium perchlorate is used in calibration of HPLC?
Erbium has a strong absorption in uv and visible range, It is used in HPlc calibration for the wavelength accuracy verification of the PDA detector.
Why is holmium used in uv calibration?
Holmium oxide is used as standard reference to check wavelengts.
Why holmium oxide is used in calibration of uv?
Holmium oxide is used in calibration of UV spectrophotometers because it has well-defined absorption peaks at specific wavelengths in the UV range. These peaks can serve as reference points for calibrating the instrument and verifying its accuracy. Holmium oxide provides a reliable and stable reference for wavelength calibration in the UV spectrum.
Why is toluene in hexane used in uv calibration?
Toluene has clear absorption peaks at 266 nm and 269 nm. Hexane is only the solvent.
What would happen to large potassium magnate crystals in water after several hours?
If you think to potassium "permanganate" this compound can be decomposed under the influence of UV radiations.
