# What is lambda max of CuSO4?

## What is lambda max of CuSO4?

After determining the λmax was 635 nm for CuSO4, the absorbance of six solutions of CuSO4, ranging from 0.00 to 0.50 M, was found using a colorimeter. Graphical analysis revealed that the relationship between absorbance and concentration was directly proportional with a molar absorptivity of 2.81 M-1cm-1.

### What is the wavelength of copper II chloride?

It appears that [Cu(benz)3(H2O)2Cl]Cl has a maximum wavelength in region 870 nm (11494.25 cm-1) and a molar absorptivity of 241.96 L/mol.cm.

How do you find the lambda max of a solution?

Hence, to find this out, prepare a solution of your compound and check the absorbance over a wide range of wavelengths, ie within the capacity of your equipment. The wavelength at which the highest signal (peak) is recorded is identified as the lambda max.

Does copper absorb sunlight?

Building features made of copper, stainless steel or other metals retain the sun’s energy.

## Does copper reflect UV light?

Metals like copper or silver are never known to emit UV at room temperature. It is now possible by gamma irradiation of metal.

What is the absorbance of copper?

The complex gave a maximum absorption at λ = 485 nm with a molar absorptivity coefficient of 2.35⋅104 l/(mol⋅cm). The linear range for the copper determination is 0.63–5.04 mg/l.

Is copper carbonate soluble in water?
