The maximum wavelength of absorbance for sodium dichromate typically occurs around 350-370 nanometers (nm). This absorbance is primarily due to the presence of the chromate ion, which exhibits strong UV-visible absorbance characteristics. The specific wavelength can vary slightly depending on the concentration and the solvent used.

How many oxygen atoms in 5 g of sodium dichromate?
Sodium dichromate (Na₂Cr₂O₇) has seven oxygen atoms per formula unit. To determine the number of moles in 5 g of sodium dichromate, we first calculate its molar mass, which is approximately 261.97 g/mol. This means there are about 0.019 moles of sodium dichromate in 5 g. Since each mole contains 7 moles of oxygen atoms, the total number of oxygen atoms is about 0.019 moles × 7 × 6.022 × 10²³ atoms/mole, which equals approximately 7.98 × 10²² oxygen atoms.
How would you prepare 24-dinitrobenzoic acid from p-nitrotoluene?

What is the water of crystallization for NaCr2O7H2O?
The water of crystallization for sodium dichromate monohydrate, represented as NaCr2O7·H2O, is one molecule of water (H2O) per formula unit of sodium dichromate. This means that for every NaCr2O7 unit, there is one water molecule that is incorporated into the crystal structure, contributing to the overall stability and properties of the hydrate.
